Abstract:
A supported NiCl2- gaseous HC1 catalyst was used in the hydro-denitrogenation reactions of indole, a
nonbasic compound, and quinoline, a basic compound. The reactions were carried out at a reactor
temperature of 400&deg,C; a reactor pressure of 850 psig; space velocities of 4.0, 1.6, 1.0, and 0.7275
LHSV; a hydrogen rate of 500 SCF/bbl of liquid feed; a chloride to nitrogen content of eight to one;
and using p-xylene as the carrier oil.
Nitrogen compositions were determined by a Kjeldahl analysis and a Mohr test was used to determine
chloride contents. The amine forms of basic and nonbasic nitrogen compounds from indole and
quinoline runs were isolated. These compounds were then identified using gas chromatography and
mass spectrometry.
In this research, nitrogen was found easier to remove from the product oil of quinoline than indole at
4.0 LHSV. However, little difference, was' observed for lower -space velocities.
Different reaction mechanisms were proposed for the denitrogenation of indole and quinoline. It
appeared that hydrochloride intermediates are present in the reaction sequences and that nitrogen leaves
the reaction zone as ammonium chloride. Also, possible limiting steps in the reaction sequences were
proposed. In presenting this thesis in partial fulfillment of the require­

ABSTRACT
A supported NiClg - gaseous HCl catalyst was used in the hydrodenitrogenation reactions of indole, a nonbasic compound, and quinoline,
a basic compound.
The reactions were carried out at a reactor tempera­
ture of 400°C; a reactor pressure of 850 psig; space velocities of 4.0,
1.6, 1.0, and 0.7275 LHSV; a hydrogen rate of 500 SCF/bbl of liquid feed;
a chloride to nitrogen content of eight to one; and using p-xylene as the
carrier oil.
Nitrogen compositions were determined by a Kjeldahl analysis and
a Mohr test was used to determine chloride contents.
The amine forms of
basic and nonbasic nitrogen compounds from indole and quinoline runs were
isolated.
These compounds were then identified using gas chromatography
and mass spectrometry.
In this r e s e a r c h n i t r o g e n was found easier to remove from the product
oil of quinoline than indole at 4.0 LHSV. However, little difference,
was' observed for lower -space velocities.
Different reaction mechanisms were proposed for- the denitrogenation
of indole and quinoline. It appeared that hydrochloride intermediates
are present In the reaction sequences and that nitrogen leaves the
reaction zone as ammonium chloride. Also, possible limiting steps in the
reaction sequences were proposed.
I- INTRODUCTION
A.
BACKGROUND
Indole and quinoline are heterocyclic nitrogen compounds which have
been found in fossil fuel stocks.
Indole, a nonbasic compound, has been
isolated in petroleum crude oil'(28) and in coal tar (3 ).
Quinoline, a
basic compound, has been identified in crude oil (2k, 28), coal tar (3),
and in hydrocracked shale oil (4, 7)•
The structure and other signifi­
cant data on both these compounds as well as on other important nitrogen
bases and nonbases are presented in Figure I.
Nitrogen compounds are' not desirable in fossil fuel stocks.
There
is now: much evidence to suggest that the nitrogen in fuels is as important
as the nitrogen in air in the formation of nitrogen oxides during combus­
tion (.10, 3l).
Nitrogen oxides in the presence of sunlight undergo a
photochemical reaction with hydrocarbons to form smog.
Also, in the
petroleum industry, nitrogen is a poison for many catalysts.
Its effect
is most notably seen in catalytic reforming where nitrogen decreases the
isomerization efficiency of dual-functional catalysts (2, 12, 15).
Today, with the United States experiencing a domestic shortage of
production crude oil, different sources of energy must be found.
One
potential source is the Green River shale oil formation of Colorado, Utah
and Wyoming.
It contains an estimated one trillion barrels of oil.
However, it also contains 2.k percent nitrogen (?)•
Before this oil can
be utilized, the nitrogen content must be reduced considerably.
Hydrodenitrogenation has been found to be the best way of removing
nitrogen from petroleum stocks (12).
In this destructive hydrogenation

process the most widely used catalysts are cobalt molybdate, nickel
molybdate, and nickel tungsten sulfide.
These catalysts systems
generally denitrogenate nonbasic compounds easier than basic ones (12).
Also, most nitrogen from these treatments ends up as ammonia.
These
systems are also better suited for desulfurization than denitrogenation.
This department, in hope of finding a better denitrogenation
catalyst system, has been, doing work on a niekelous chloride-gaseous
hydrochloric acid catalyst system since 1966 (11,19,20).
This work has
primarily been aimed at determining, the operating variables for maximum
denitrogenation.
However, work has also been done to determine the
relative ease of denitrogenating a number of heterocyclic nitrogen
compounds.
1)
This system has shown some unusual characteristics:
Basic compounds are generally easier to denitrogenate
than nonbasic compounds.
2)
There is a higher denitrogenation than desulfurization
activity.
3)
Hydrochloride intermediates are suspected in the reaction
sequence.
H)
Nitrogen appears to leave the reaction zone as ammonium
chloride.
The work detailed in this report has been done to find a mechanism to
account for these characteristics.

- 5 is a very important concept.
Generally, heterocyclic compounds are
arbitrarily classified as "basic" or "nonbasic" by their ability to
react with a perchloric acid-acetic acid solution.
Basic compounds
can react with this solution and nonbasic compounds can not.
The reason for this difference can be found by studying the
electronic configurations of the pyrrole and pyridine carbon and
nitrogen atoms.
As can be seen from Figure I, pyrrole and pyridine
are very similar in molecular structure to indole and quinoline
respectively.
In pyrrole, a nonbasic compound, the electronic configurations
the carbon and nitrogen atoms are as follows:

Pyrrole and indole while not forming salts with even strong acids cannot
be considered acids so the classification of "nonbase" will be used for
these compounds.

RESEARCH OBJECTIVES
The primary objective of this research was to identify intermediate
compounds in the hydrodenitrogenation of indole and quinoline which then
could be used to speculate as to possible reaction mechanisms.
Other
objectives were to prove the existence of. ammonium -chloride and hydro­
chloride intermediates.

EXPERIMENTAL APPARATUS, PROCEDURE AND ANALYSIS
MATERIALS
I.
Charge Stock
The two nitrogen compounds used in this work were indole and
quinoline.
They were chosen because they are both found in coal
tar and crude oil and because they are both available in large
quantities, in pure form, and at reasonable prices. The nonbasic
compound indole was obtained in reagent grade from the Aldrich
Chemical Company.
The basic compound quinoline was supplied by
the J. T. Baker Chemical Company in reagent grade.
The carrier oil initially chosen was "Peneteck" a commercial
mineral oil produced by the Pennsylvania Refining Corporation.
However, this oil proved to be unuseable since it interfered with
some nitrogen peaks on the chromatograph.
Therefore, p-xylene, a
compound with a retention time less' than the nitrogen compounds was
selected.
This compound was obtained 99% pure from the Chevron
Chemical Company.
The charge stock also included methylene chloride and hydrogen.
Some of the hydrogen reacted with the methylene chloride to form
gaseous hydrochloric acid under the reactor conditions.
Hydrogen
was supplied in 2000 psig cylinders by H . R. Oxygen Supply of
Billings,
Montana.
The methylene chloride was obtained in
reagent grade from the J. T. Baker Chemical Company.

The catalyst used in this work was prepared hy Fedoruk (ll).
He impregnated HiClg on a 1/8 hy 1/8 inch Harshaw alumina pellet.
He determined the nickel content of the pellets to he 7.72 percent.
By using only this catalyst, the nickel content of the pellets was
eliminated as a variable in this work.
The Norton Company supplied the filler.
It consisted of inert
alumina pellets and was used to support the catalyst pellets in the'
reactor.

the bottom of the aluminum block was a thermowell.
One iron-constantan
thermocouple measuring a temperature in the middle of the reactor
supplied the input signal to the on-off controller.
Three other
thermocouples connected to a Leeds and Worthrup indicating potentiometer
measured the temperature at the t o p , middle and bottom of the reactor.
The product after leaving the reactor passed through a Grove back­
pressure regulator and into a flask.
The liquid was collected in the
flask and the gas first bubbled through a caustic bath to remove the
acidic vapors and then was vented.
C.
OPERATING PROCEDURE
I.
Process Conditions
In order to identify intermediate products from the reactions,
the system was operated at less than optimum nitrogen removal
conditions.
These reduced conditions were:
a)
The reactor temperature was 400°C.
b)
The reactor pressure was 850 psig.
c)
Hydrogen rate was 5000 SCF/BBL of feed.'
d)
The nitrogen content of the feed was 0.66 percent.
e)
The chloride to.nitrogen ratio was eight to one.
f)
Liquid feed pumping rates were 4.0, 1.6, 1.0, and 0.7275
LHSV for-the quinoline runs and 4.0, L. 6 , and 1.0 LHSV
for the indole runs.
2.
Reactor Charging
The 250 ml of filler and 100ml of catalyst used each run were
dried at 400°C for 2k hours.
These were cooled in a desiccator.
In charging the reactor, half of the filler was poured down the
inverted pipe with the thermowell already in place.
Then the
catalyst, followed by the remaining filler, was added.
After each
layer was in place, the side of the pipe was tapped to insure
complete and uniform settling.
Finally, a glass-wool plug and a
stainless steel coll were positioned to support the catalyst and
■filler as the pipe was turned upright.
Then, with the pipe
enclosed in an aluminum block, the heating coils were turned on
and the reactor was brought up to temperature.
3.
Reactor Operation
With all fittings tightly sealed and the reactor at ^OO0G ,
the back-pressure regulator was pressurized to about 825 psig with
hydrogen.
The reactor itself could then be pressurized to 85O psig
inlet pressure-with the selected hydrogen gas flow.
for gas leaks, the feed pump was started.
After checking
By measuring the
volumetric feed rate of the oil, the adjustable stroke on the
piston pump was set to give the desired space velocity.
During
the run, the temperatures in the reactor were closely watched and
the two manual variacs were adjusted to keep the reactor top
and bottom temperatures as close to 400°C as possible.
To insure
- 15 a completely "lined-out" catalyst, 500 ml of feed were reacted
before any product was sampled.
After 200 ml of product oil
were collected, the reactor was "shut down."
This process
consisted of shutting off the hydrogen rate, the feed pump,
and the heating coils..
Also, the reactor system was depressurized.
When the system had cooled, the reactor was emptied and the
entire system was cleaned.
The catalyst and support were
discarded without being reused.

The reactor tube was washed with
With the indole runs material which had
accumulated in the bottom of the reactor and on the support coil
was also saved for further analysis.
D.
ANALYTICAL METHODS
The nitrogen content of the samples was determined by a standard
Kjeldahl method (l8 ),
Two analyses of each sample were run and an
average of the two analyses was recorded.
Kel-paks obtained from
Matheson Scientific Company which contained a weighed amount of K^SO^
and HgO proved to be time saving.
The chloride content of samples was
determined by the Mohr volumetric method (33).
The nitrogen compounds in the product samples were separated into
basic and nonbasic fractions and then concentrated according to a
method outlined by Hartung and others (l4).
These concentrates were
tentatively identified chromatographically.
The unknown concentrates
were injected into the chromatograph and the peaks observed were compared
for retention time with known compounds.
Also, retention data from
- 16 Poulson (24) proved to be quite useful.
The three columns which
proved to be most successful were given in Table I.

The KOH treatment was applied as outlined by Smith and Radford (26)
to reduce severe tailing of the nitrogen compounds which was encoun­
tered on untreated columns. The treatment was very successful. The
chromatograph used was a Varian Aerograph 200.
The recorder was a
Sargent Model SR.
The primary tool for identifying the nitrogen compounds was
mass spectrometry.
Two mass spectrometers were used in this research.
One was a Varian Model Ch5 which was located in the Chemistry Depart­
ment of Montana State University,
The other was a Variant Model MAT
111 located in the Chemistry Department of the University of Montana.
Both analyzed samples which had passed through one of the columns
described in Table I.
In this way, the samples were separated into
individual compounds before they were analyzed - unless two or more
compounds had identical retention times.

RESULTS M D DISCUSSION
Nitrogen and Chloride Analyses'
After every quinoline or indole run, a white crystaline solid was
found deposited on the upper section of the support coil and a large amount
of brown solid was found in the bottom of the reactor.
Previous workers
(ll, 19) felt that the white crystal was probably ammonium chloride.
The
data in Table 2 confirms their hypothesis.

The slight deviations of the experimental values from the actual values are
likely due to small bias in the experimental techniques.
Also, ammonium
chloride sublimes at 3^0°C at atmospheric pressure and so would be expected
to .sublime in the upper section of the cooling portion of the reactor.
Previous workers (ll, 19) felt that the brown solid might be hydro­
chloride salts of the basic nitrogen compounds.
Data taken in this work
supports this hypothesis.- For each of the nine indole runs the nitrogen and
- 18 chloride contents of the solid were found.
The nine nitrogen analyses
showed an average content of 12.67% with a standard deviation of 0.365.
The nine chloride analyses showed an average content of 39.46% with a
standard deviation of 1.379.
Nitrogen and chloride analyses were not run
on the solid from the quinoline runs.
It must he noted here that nitrogen
and chloride analyses were calculated on a different basis.
The chloride
samples were dried at IlO0C for one hour before being weighed, but the
nitrogen samples were not dried.
It will be shown later in this report that aniline was identified in
both the quinoline and indole runs.

This compound has 10.81%
These values are lower than the experimental
However, if some ammonium chloride were present in the brown solid
and if one takes into account the different basis for the nitrogen and
chloride analyses, the experimental values are possible.
In the 4.0 and 1.6 LHSV quinoline runs and the 4.0 LHSV indole runs,
some of the hydrochloride salt, in the form of a very viscous liquid,
flowed into the product flask.
The salt did not usually enter the product
flask until about 500 mis, of feed had been reacted.
The constrictions in
the bottom of the reactor and the back-pressure regulator obviously
restricted the flow of the salt.
Since not all of the salt made it into
the product, flask, it was .decided, to,:exclude the salt in the product flask
from the samples for nitrogen analysis.
This was accomplished by simply
decanting the oil product off the very viscous salt.

Identification of Compounds
1.
Introduction
Figure 8 is a chromatogram of a known mixture of basic compounds.
It shows that several compounds can have identical retention times.
Therefore, in this research, mass spectra data was essential to
identify compounds with certainty.
This figure also shows that ^-substituted aniline is more strongly
absorbed on Carbowax 2CM than a ring-substituted aniline.
o-Methyl-
aniline has a longer retention time than N-methylaniline.
Likewise,
p-propy!aniline has a longer retention time than N-n-propylaniline.
The reason for this is that- a primary nitrogen is more strongly
absorbed than a secondary nitrogen.
It should be noted that in subsequent identification of basic
nitrogen compounds the amine forms of the compounds are identified.
However, as was shown earlier, the basic nitrogen compounds leave
tlie reactor in their hydrochloride salt forms.
The amines are formed
by treating the salts with a dilute potassium hydroxide solution.
In this paper,, in order to avoid confusion between chromatogram
"peaks" and mass spectrum "peaks" the former will be referred to as
"traces."

A comparison of

O-methylaniline and N-n-propylaniline.
However, the mass spectrum

the base peak for the compound is 106.
As can be seen from Table 3,
This base peak is typical of
- 27 substituted anilines (5).
The parent peak of 133 with a large 132
peak is very similar to I ,2,3,H-tetrahydroquinoline.
However, the
retention time is wrong for this compound to be 1 ,2 ,3 ,4-tetrahydroquinoline.
Therefore, a compound must be found with a molecular weight of
1.2.3.4- tetrahydroquinoline and a retention time of N-n-propylaniline.
The obvious answer is a N-substituted aniline with an unsaturated
three-carbon side chain.
One possible candidate is N -allylaniline.
This compound could easily be formed by opening the pyridine ring of
1.2.3.4- tetrahydroquinoline.
1,2,3,4-Tetrahydroquinoline
N-Allylaniline
Traces 5 and 6 were not large enough to be analyzed on the mass
spectrometer but these might be o-methylaniline and o-ethylaniline
based on retention times.
The mass spectrum for trace T is listed in

in trace 7
Table U shows that trace 7 has more than one compound.
However,
it also shows that the major compound in trace 7 is very similar to
p-propylaniline.
A mass spectra comparison with N-n-propylaniline
would be good, but the retention time, would rule it out.
However, the
retention time for p-propylaniline corresponds to trace 8 and not trace
7.
But o-propylaniline could have a retention time like that of trace
7 and would have a similar mass spectrum.
With the propyl group in
the ortho position to the primary nitrogen there could be a shielding
effect to reduce the absorption of the nitrogen.
Thus o-propylaniline
probably has a shorter retention time than p-propylaniline.
Un­
fortunately, no o-propylaniline was available to test the hypothesis.
Trace 9 could not be isolated sufficiently from trace 8 to get a
separate mass spectrum.
However, the mass spectrum of trace 8 has
- 29 contamination peaks at lk2 and 1^3 corresponding to 15% and 22%,
respectively, of the quinoline base peak, 129.
Peaks 11+2 and 11+3
correspond to a methyIquinoline.
When programming the column temperature on the 5-foot Carbowax
column, traces were visible beyond I ,2 ,3 ,4-tetrahydroquinoline which
were too broad on the large column to be seen.
These traces were
invariably composed of more than one compound.
However, large
mass peaks were observed at 156, 157, 170 and 171.
The first two
numbers correspond to a dimethy!quinoline or an ethylquinoline.
The
last two correspond to a trimethylquinoline, a methylethylquinoline,,
or a propylquinoline.
It is interesting to note that Ryffel (25) identified aniline,
o-methylaniline,oo-ethylaniline, o-propylaniline, quinoline and
1, 2j3,l+-tetrahydroquinoline in the product oil of a destructive
hydrogenation of quinoline over a cobalt-molybdate catalyst.

However,
with the quinoline runs the nonbasic compounds were such a m i nor'

The mass to charge

No p-xylene dimer was available to compare for retention time or mass
spectrum, but it is strongly suspected that the trace is the dimer.
Trace 5 seems to be a methylindole.

The one major surprise of this listing is the absence of indole and
indoline from the indole slate.
This fact combined with the fact that
quinoline and 1 ,2 ,3 ,4-tetrahydroquinoline are present in the quinoline
slate suggests that different mechanisms are involved in the hydrodenitrogenation of quinoline and indole and that basicity must play
an important role in this difference.
C.
Reaction Mechanisms
The nickelous chloride-gaseous hydrochloric acid catalyst behaves as
dual functional catalyst.
It contains sites for a hydrogenation function
and for an acid function.
The hydrogenation function is responsible for
hydrogenation and dehydrogenation reactions.
The acid function is
responsible for cracking, isomerization,, and polymerization reactions (2 ).
With this catalyst system, the following sites for hydrogenation and
acidic activities are possible:
-UoHYDROGENATION
ACIDIC
I)
Ni
HCl
2)
H+ (NiCl3 )-
H+ (NiCl3 )-
3)
H+ (NiClgOH)-
H+ (NiClgOH)
These site combinations all involve nickel and hydrochloric acid.
The
reason for this is that McCandless (19, 20) showed that "a minimum amount
of nickel and a minimum partial pressure of HCl are required for good
denitrogenation activity."
With the first of the above site combinations the hydrogenation
/
functions would take place at a nickel site on the catalyst surface.
The
acidic functions could take place either where hydrochloric acid is
absorbed on the catalyst surface or possibly in the gas phase with gaseous
hydrochloric acid.
In either case, the nitrogen compound would have to
migrate or diffuse from the nickel site to the hydrochloric acid site in
order for the denitrogenation reaction to go to completion.
With the last two active sites an entire denitrogenation reaction
could conceivably take place at one location on the catalyst surface.

Unfortunately, this research did not obtain the type of data
necessary to identify the site combination actually present on the surface
of this catalyst.
Using•the product slates in Table 11 possible reaction mechanisms for
the denitrogenation of quinoline and indole were postulated in Figures
and 15, respectively.
These mechanisms are very similar.

difference is that indole must first be reduced to a basic compound
before it can react with the active site H+ '(NiCl ) .
being a basic compound can react directly.
However, quinoline
One might speculate that it
is this reduction step which causes indole to be more difficult to
denitrogenate at 4.0 LHSV than quinoline.
However, since indole was not
identified in the 4.0 or 1.6 LHSV product oil from the indole runs, it is
likely that indole was reduced quickly and irreversibly.
Therefore, the
reduction step would not be the limiting step in the reaction sequence.
In Figure I4
the products of reactions 1,3,4 and 5 were identified in
their amine forms.
Also, ammonium chloride., one of the products of reaction
6 , was identified.
I ,2-Dihydroquinoline was not identified but this
compound has been found in the product of a mild reduction of quinoline (25).
It is likely that the salt of I ,2-dihydroquinoline is formed in the reduction
of quinoline but that it is immediately reduced to the salt of I ,2 ,3 ,4-tetrahydroquinoline.
In Figure 15, the products of reactions 3, 4, 5 and the ammonium
chloride from reaction 6 were identified.

mechanisms could be possible.
However, other

reaction sequence.
This would mean that reaction 5 would not procede.
Most of the aniline would then come from reaction 4.
A sure way to test
this mechanism would be to react the salt of o-methylaniline at the same
reactor conditions as indole.
Then a comparison of the reaction rates
and product slates would indicate if step 5 is in the reaction sequence.
As such runs and analyses were not made in this research, it is impossible
to positively identify the reaction sequences for the denitrogenation of
indole and quinoline,
The presence of methylated quinolines and indoles in the quinoline
product and high molecular weight anilines, carbazoles, and methylated
indoles in the indole product is the result of destructive alkylation.
Hydrocarbons from cracking reactions react with anilines, indoles and
quinolines.
Methylated indoles and quinolines are harder to denitrogenate
than indole and quinoline (12).
This means that complete denitrogenation
of quinoline and indole would be difficult even at long reactor space time.
Since alkylated anilines were identified in the product oil of indole
and not quinoline runs this would suggest that the denitrogenation of indole
is limited by one of the aniline or methylated aniline reactions.
The
salts of these compounds must have a long residence time in the reactor to
allow alkylation to take place.
Using similar logic, it would appear that quinoline must have a long .
residence time in the reactor to allow quinoline to be .alkylated.
This
would suggest that either the initial reaction of quinoline to form the
-U t salt with the active site or the reduction of this salt to the salt of
I, 2-dihyroquinoline is the limiting reaction.
The former case seems to
he more likely.
If in future work even more reduced conditions were selected and the
product slates for these conditions were obtained for a number of space
velocities then one could speculate with more assurance as ,to possible
limiting reactions.
V.
SUMMABY
and
conclusions
The following conclusions can he drawn from this work on the
hydrodenitrogenation of indole and quinoline:
1.
It is easier to remove nitrogen from the product oil of quinoline
than indole at 4.0 LHSV, hut at lower space velocities little
difference is observed.
2.
Nitrogen leaves the reaction zone as ammonium chloride.
3.
Hydrochloride intermediates appear to he present in the reaction
sequence.
4.
The amine forms of basic and nonbasic nitrogen compounds from
indole and quinoline runs can he isolated.
5.
Different reaction mechanisms with different limiting steps must
he proposed for the denitrogenation of indole and quinoline.
6.
Destructive alkylation reactions seem to occur.
7.
Some of the p-xylene appears to dimerize.
VI.
RECOMMENDATIONS FOR FUTURE WORK
Future work should "be aimed at testing the hypotheses proposed in
this report concerning the type and location of the active sites, the
reaction sequences, and the limiting reactions.
The three programs
outlined "below might be useful.
1.
An intensive analysis of reacted catalyst pellets for nitrogen,
nickel, and chloride content might shed some light on the type
and location of the active sites.
2.
Reaction of proposed intermediate compounds a t .the same reactor
conditions as indole and quinoline and subsequent comparison of
reaction rates and product slates would test hypotheses concerning
reaction sequences.
3.
Analysis of rate data and product slates from the denitrogenation
of quinoline and indole at a number of space velocities and at
less severe "reduced" conditions than those of this research would
test hypotheses concerning limiting reactions in the reaction
sequence.

Mass Spectrometry
In a mass spectrometer a beam of electrons bombards a molecule.
The molecule is broken into ions.
The ions have a particular ratio
of mass to electronic charge, or m/e ratio.
Most ions have a charge
of one so that means that the m/e ratio is the mass of the ion.
A
’’molecular ion" or "parent ion" is an ion which has not lost any
mass and has lost only one electron:
+
-
M
+
e
------M
-
+
Se
Molecular
Ipn
A table or plot of all m/e ratios found for a particular
molecule and the respective relative intensities is called a "mass
spectrum".
In a plot of the m/e ratios the peak with the largest
intensity" is called the "base peak".
It is given a value of 100
and all other relative intensities are calculated from it.
the base peak occurs at the molecular ion.
Often
A mass -spectrum for a
molecule can be highly characteristic of that molecule (3)•
This
can be seen by looking at the API mass spectrums (6) and the experi­
mental mass spectrums which follow.
Thus the mass spectrometer is
a very powerful tool for identifying unknown compounds.
