Introduction Vaporization enthalpies are important thermodynamic properties of the condensed phase. Vaporization enthalpies are used frequently in adjusting enthalpies of formation of liquids to the standard state and in evaluating environmental transport properties.1,2 To the chemical engineer, the magnitude of this property needs to be taken into consideration in designing equipment for chemical processing and synthesis. Thus vaporization enthalpy data are of interest at a variety of temperatures. As a consequence, there is a wealth of information in the literature that covers measurements over a broad range of temperatures. The data covered by this compendium include as much of the spectrum as was available to us. Our interest in vaporization enthalpies goes back nearly two decades. Our primary focus in measuring vaporization enthalpies was as a means of adjusting enthalpies of formation of liquids to the standard state and in conjunction with fusion enthalpies to adjust solids in a similar fashion.3 Since then we have focused our attention on their estimation,4 and assessment.5 In parallel studies, compilations of available sublimation and fusion enthalpies were also initiated.6,7 A 520 522 524 525 526 527 a兲 Author to whom correspondence should be addressed; electronic mail: jsc@umsl.edu b兲 Electronic mail: acree@unt.edu © 2003 American Institute of Physics. 0047-2689Õ2003Õ32„2…Õ519Õ360Õ$37.50 inorganic compounds, 1880–2002. . . . . . . . . . . . . . 8.

Combined with fusion and sublimation enthalpies appropriately adjusted to T⫽298.15 K, vaporization enthalpies ⌬ vapH m (298.15 K), complete a thermochemical cycle that can be used to assess the quality of the available data. Application of this thermochemical cycle is illustrated below. A goal of the present contribution has been to provide an exhaustive coverage of the literature from about 1880 to 2002; regrettably however, this compilation is probably still incomplete. 2. Reference Materials for Vaporization Enthalpy Measurements Calibration is a fundamental requirement in every thermochemical measurement of vaporization enthalpy. Regardless of which technique is used, the measurement ultimately depends either directly or indirectly on vapor pressure. Vapor pressures of liquids vary over many orders of magnitude. An experimental technique calibrated with a standard in one pressure or temperature regime does not in itself guarantee the same accuracy in another. Substantial variations in vaporization enthalpy are revealed in the tables that follow. This variance clearly establishes the importance of documenting the accuracy of the measurements through the use of appropriate reference materials that approximate the temperature and pressure regimes of the measurements of interest. A series of compounds have been recently proposed as reference materials for vaporization enthalpy.5 These have been classified as primary, secondary, or tertiary reference materials, on the basis of various criteria. The materials classified as primary and secondary reference materials are listed J. Phys. Chem. Ref. Data, Vol. 32, No. 2, 2003 in Table 1. The temperature range, the corresponding vapor pressures, and the recommended molar vaporization enthalpies at T⫽298.15 K are also included in the table. Some of these reference materials are solids at T⫽298.15 K and therefore the vaporization enthalpies are hypothetical values. The reader should consult the literature cited at the bottom of the table to obtain the vaporization enthalpy at the temperature of interest. 3. Heat Capacity Adjustments Vaporization enthalpies, like their sublimation counterparts, are measurements based on mass transport and as such are directly or indirectly dependent upon vapor pressure. The vapor pressure of different liquids at a given temperature can vary many orders of magnitude. In order to obtain a reasonable amount of mass transport, it is frequently necessary to conduct these measurements at temperatures that differ substantially from the standard reference temperature, 298.15 K. The actual temperature of measurement depends on the sensitivity of the instrument or apparatus and the properties of the substance of interest. Vaporization enthalpy measurements are often conducted as a function of temperature. The magnitude of the vaporization enthalpy is dependent on temperature. Figure 1 and Eqs. 共1兲 and 共2兲 illustrate the origin of this temperature dependence in terms of a thermodynamic cycle. If the heat capacities of the liquid and gas phase are known, C p l and C p g , respectively, then the vaporization enthalpy at T⫽298.15 K can be related to the experimental measurements by using Eq. 共1兲. This equation, generally referred to as Kirchhoff’s equation, can be used to adjust sublimation enthalpy measurements to any reference temperature. The term T m represents either the temperature ENTHALPIES OF VAPORIZATION 521 temperature. In some cases experimental data have been used for C p l and in other cases both C p l and C p g have been estimated. The reader is encouraged to refer to the original literature for details. In an effort to provide some assistance to the reader in this regard, a brief discussion of one of the group additivity methods that are available for estimating the heat capacity of liquids is included below. This is followed by an illustration of how this value can be used in conjunction with Eq. 共3兲 to provide temperature adjustments. FIG. 1.

Treating the heat capacities of the two phases as independent of temperature and integrating Eq. 共1兲 results in Eq. 共2兲. Since the magnitude of the heat capacity of the gas phase is usually smaller than that of the liquid phase 共l兲, vaporization enthalpies increase with decreasing temperature. Experimental heat capacities for many liquids at T ⫽298.15 K are available.8 Experimental gas phase heat capacities for compounds that are liquids at T⫽298.15 K are unavailable and generally need to be estimated. Gas phase heat capacities can be calculated from statistical mechanics or estimated by group additivity methods. A number of group additivity methods have been developed to estimate gas phase heat capacities.9,10 However, group values for some functional groups are not available. Equation 共3兲 is an example of an attempt to circumvent the lack of sufficient group values.11 The term C p l (298.15 K) refers to the heat capacity of the liquid at T⫽298.15 K. This term may either be estimated or experimental values may be used if available.

The vaporization enthalpies are reported at the mean temperature of measurement wherever possible. This allows the reader to verify the reported data and to adjust for temperature in a consistent manner. Authors have applied different methods to adjust for 4. Group Additivity Values for C p l „298.15 K… Estimations Tables 2A and 2B lists a set of group values that can be used in estimations of C p l (298.15 K). The groups and their corresponding values are identified by italics. A hypothetical molecule is given in Fig. 2 that identifies each hydrocarbon group. The functional groups listed in Table 2B are self explanatory. The R terms in this table represent variable groups and are not included in the value. Values in brackets should be considered as tentative assignments. The use of these group values is illustrated with the examples in Table 3. Estimations of C p c (298.15 K) for these compounds follow the same protocol. Groups are defined on the basis of their substitution and hybridization patterns. These groups are further subdivided into cyclic, acyclic and aromatic categories. The estimation of C p l (298.15 K) for propionic acid illustrates how directly C p values can be estimated. Identification of the appropriate group is important. Although not shown in Table 3, the same protocol is used for estimating C p c (298.15 K). Estimation of the heat capacity of piperadine is similar. In this case it is important to use the appropriate cyclic group. Once the proper groups are identified, the estimation is direct. Di-tbutyl ether is estimated in a similar fashion. Benzothiazole illustrates the estimation of an aromatic molecule containing a heterocyclic ring. The aromatic ring carbons are selected based on their substitution pattern; the sulfur and nitrogen atoms of the thiazole ring are identified as cyclic atoms; the nitrogen atom is identified on the basis of its hybridization and substitution pattern. 2-Methylcyclohexanone is another example of an estimation of a cyclic molecule. This estimation includes the contributions of a cyclic carbonyl, four cyclic methylene groups, a methyl, and a cyclic tertiary methine group. The estimation of limonene illustrate an example of a molecule that contains both cyclic and acyclic double bonds. Additional examples can be found in the literature.4,11 Heat capacities calculated according to the protocol just described have been used when necessary in conjunction with Eqs. 共4兲–共6兲 to adjust vaporization, sublimation, and fusion enthalpies to 298.15 K. These temperature adjustments are necessary in illustrating the thermochemical cycle described below. Equations 共4兲–共6兲 have been used in those cases where the measurements were referenced to some other temperature J. Phys. Chem. Ref. Data, Vol. 32, No. 2, 2003 522 J. S. CHICKOS AND W. E. ACREE, JR.

It should be emphasized at the start that internal consistency within a cycle does not guarantee that all the data are necessarily of high quality. Sublimation enthalpy is related to the sum of the fusion and vaporization enthalpies, Eq. 共7兲, provided all are referenced to the same temperature.

A Thermochemical Cycle: Sublimation, Vaporization, and Fusion Enthalpies 共6兲 An uncertainty 共⫾2 兲 of one third the temperature adjustment has been associated with the use of Eqs. 共5兲 and 共6兲 in Table 4. The uncertainty has been assigned arbitrarily. FIG. 2. A hypothetical molecule illustrating the different hydrocarbon groups in estimating C p . 共7兲 the two enthalpies on the right hand side of the equation. Since fusion enthalpies of solids usually decrease when adjusted to 298.15 K, the latter contributes a smaller amount to the sublimation enthalpy, particularly if the melting point of the material is high. Thus an accurate vaporization enthalpy can tolerate a less accurately determined fusion enthalpy. This is fortunate since as discussed below, there is a physical basis for variance in fusion enthalpy. Many solids exhibit polymorphism or undergo solid-solid phase transitions. These may occur unnoticed. Solid-solid phase transitions occurring below T⫽298.15 K generally do not pose a problem if the vaporization and sublimation enthalpy measurements are conducted at temperatures above the phase change. Enthalpic differences between polymorphic forms generally tend to be small in relation to solid-gas, liquid-gas transitions. Since the smaller ⌬ fusH m (298.15 K) term in Eq. 共7兲 is the one affected by polymorphism, this phenomena should not have a large effect on the quality of the thermochemical cycle, even if the sublimation and fusion enthalpy measurements are conducted on different polymorphic forms. In many cases the sublimation enthalpy measured directly should compare favorably with the sum of the fusion and vaporization enthalpy. Yet often this is not the case. The results given in Table 4 illustrate some of the situations that can arise when constructing a thermochemical J. Phys. Chem. Ref. Data, Vol. 32, No. 2, 2003 524 J. S. CHICKOS AND W. E. ACREE, JR.

The sublimation enthalpy of p-nitroaniline has been measured frequently and reproducibly. The value of 共100.9⫾1.0兲 kJ mol⫺1 is the mean value of nine measurements. Two measurements of the fusion and vaporization enthalpy are also available. Both fusion enthalpies are in good agreement with each other; the mean value is reported in Table 4. Comparison of the vaporization enthalpies at T⫽298.15 K results in values with a 12 kJ mol⫺1 discrepancy. In this instance the experimental sublimation enthalpy falls halfway between the two values calculated by Eq. 共7兲. The experimental data suggest a vaporization enthalpy of 85.5 kJ mol⫺1. This is an instance where the vaporization enthalpies are in disagreement; disagreement between sublimation enthalpies is the more common occurrence. Data for 1,6-hexanedioic acid represents results that are more typical. The fusion and vaporization enthalpies have been measured once while the sublimation enthalpy has been reported three times. In this instance good agreement is obJ. Phys. Chem. Ref. Data, Vol. 32, No. 2, 2003 served between three of the four sublimation values. Acetanilide provides a different but similar example. The sublimation enthalpies calculated using Eq. 共6兲 are slightly larger than the two direct measurements. The data suggest a vaporization enthalpy of 73.9 and a sublimation enthalpy of 90 kJ mol⫺1 at T⫽298.15 K. The vaporization and sublimation enthalpies of 4-chlorobiphenyl have been reported a number of times. One set of sublimation enthalpies cluster around 83 kJ mol⫺1 and the other around 75 kJ mol⫺1. A distinction between these two possibilities is possible by examining the vaporization enthalpies of the isomeric 2- and 3-chlorobiphenyls 共see Table 6兲. The vaporization enthalpies of these isomeric materials would be expected to be similar.

The scatter of data obtained for methyl hexadecanoate illustrate another common situation that can arise when data from the literature are examined. Two fusion enthalpies and several vaporization enthalpies have been reported which are not in particularly good agreement. Using the value of the sublimation enthalpy as a guide, consistent results are obtained if the fusion enthalpy of 54.7 kJ mol⫺1 共298.15 K兲 is combined with the mean of the last three vaporization enthalpies, 98.3⫾5.3 kJ mol⫺1, resulting in a sublimation enthalpy of 152.9⫾5.4 kJ mol⫺1. 6. Estimation of Vaporization Enthalpies Vaporization enthalpy is a property that is successfully modeled by various computational methods. Many estimation methods in the chemical engineering literature have been developed to provide vaporization enthalpies near or at the boiling point and are accurate to a few %. Some require critical constants and other parameters that may have to be estimated themselves. A summary of some of the existing methods and their applications can be found in the book edited by Lyman et al.10 共see also Ref. 15兲. The estimation of vaporization enthalpy at or near the boiling point continues to be a topic of recurring interest.16 –23 A number of methods and equations for the estimation of vaporization enthalpies at T⫽298.15 K have also been developed. Some model vaporization enthalpies on concepts of group additivity while some are based on other thermodynamic principles.24 –35 Details on the application of some of these methods in estimating vaporization enthalpies are available.4,10,25 7. Vaporization Enthalpy Compendium Vaporization enthalpies reported from the 1880s to 2002 are included in Tables 6 and 7. Table 5 contains a listing of the acronyms and abbreviations that are used in both tables. Table 6 contains vaporization enthalpy data for organic compounds; Table 7 contains similar information for a selected number of organometallic and inorganic substances. Information in the tables is organized as described below. J. Phys. Chem. Ref. Data, Vol. 32, No. 2, 2003 526 J. S. CHICKOS AND W. E. ACREE, JR. TABLE 5. A list of acronyms and abbreviations used in Tables 6 and 7 A B BG C GC GCC CGC DM DSC EB EST GS HG HSA I IPM ME MG MM NA OM RG SG STG T TE UV calculated from the vapor pressure data reported by the method of least squares calculated from the difference of the enthalpies of sublimation at temperature T, and fusion at the melting point Bourdon gauge calorimetric determination gas chromatography gas chromatography-calorimetry correlation gas chromatography diaphram manometer differential scanning calorimeter ebullometry estimated value gas saturation, transpiration Heise gauge head space analysis isoteniscope inclined piston manometry mass effusion–Knudsen effusion McLeod gauge mercury manometer not available at the time of publication oil manometer Rodebush gauge spoon gauge strain gauge tensimeter torsion effusion ultraviolet absorption Compounds are arranged according to molecular formula. The compound’s name, occasionally a synonym, and the CAS registry number are included on the first line. The range of temperatures studied is the next entry in the table. For measurements performed at a constant temperature or when not specified, this entry is left blank. The vaporization enthalpy at the mean temperature of measurement, ⌬ vapH m (T m ), is the next entry followed by the mean temperature (T m /K), an acronym or abbreviation briefly describing the type of measurement and the reference to the original work. In some cases the type of measurement was not available, or recorded. In these instances this entry was left blank. If the authors of the work have adjusted their results to 298.15 K, then this information along with the reference is entered on the third line. This information is repeated for multiple measurements. The measurements are arranged in reverse chronological order. Entries for compounds with deuterium substitution are listed after the unlabeled parent. The authors have made an effort to present the data accurately and without error. Much of the earlier data have been retrieved with the aid of existing compendia that have been published over the years. Most of these compendia include references to the original literature. A notable exception is the very useful reference Handbook of the Thermodynamics J. Phys. Chem. Ref. Data, Vol. 32, No. 2, 2003 of Organic Compounds by Stephenson and Malanowski published in 1987 by Elsevier Science Publishing Co. Some of the data included in this compendium, notably for the higher n-alkanes and haloalkanes, appears to be data that have been estimated.36,37 Estimated vaporization enthalpies are generally not included in Table 5 unless the data are reported in the Stephenson and Malanowski compendium or the source is identified. The reader should exercise some caution when using data that are not referenced to the primary literature. Additionally, some of the information has originated from non-English language journals with translations occasionally provided by the author’s students. These tables, having been complied over a period of twenty years, have gone through numerous revisions. Some errors have been corrected; however it is unlikely that all of them have been detected. The reader is encouraged to consult the original literature when using this data. Several sources of data contains vapor pressure data represented in the form of the Antoine equation 关Eq. 共8兲兴, where P represents the vapor pressure, T is the temperature in K, and A, B, and C are the Antoine constants obtained from treatment of the vapor pressure-temperature data log10 P⫽A⫺B/ 共 C⫹T 兲 . 共8兲 Vaporization enthalpies were calculated from the Antoine constants in one of two ways. A Lotus macro was written to calculate vapor pressures using the Antoine constants over a 30 K temperature range; the resulting vapor pressure– temperature data were reformulated in terms of the integrated form of the Clausius–Clapeyron equation. A ln P versus 1/T linear regression analysis provided ⌬ vapH m (T m )/R at the mean temperature, T m , of the 30 K range. The 30 K temperature range was chosen closest to T⫽298.15 K but within the temperature range specified. Alternatively, vaporization enthalpy was calculated using the Antoine constants from the following equation: ⌬ vapH m 共 T m 兲 ⫽2.303RB 关 T m / 共 T m ⫹C兲兴 2 . 共9兲 Temperatures were chosen to lie with the range of measurement, often at the mean temperature. In a number of instances, the authors only provide vapor pressure– temperature data. In these instances, a vaporization enthalpy was calculated from the data as described above. An examination of data in Tables 6 and 7 reveals that many compounds have been measured repeatedly. All the data here are treated equally; there has been no attempt to recommend or identify recommended values. A critical evaluation of the data is beyond the scope of this compendium. However, the reader should be aware of a number of critical reviews that are available. The IUPAC monograph, ‘‘Enthalpies of Vaporization of Organic Compounds by Majer and Svoboda12 is among the most extensive evaluations available. Others are included in the references associated with Tables 6 and 7. The reader is encouraged to consult these references before deciding on the best value to use.
