Applications
-Propanol is used as a solvent and an intermediate. It shows less tendency
n
to absorb water than lower alcohols, and has a considerably milder and
more pleasant odour than higher alcohols.
he main application as a solvent is in flexographic and other printing inks.
T
In the coatings industry, n-Propanol is a useful medium-volatility alcohol for
improving the drying characteristics, e. g. of alkyd resins, electrodeposition
paints and baking finishes.
It is added to cleaners, floor polishes and metal degreasing fluids and is
used as an additional solvents in the manufacture of adhesives.
-Propanol is also present in de-icing fluids and is used as extractant and
n
entrainer in azeotropic distillation.
-Propanol is a feedstock in the manufacture of insecticides, herbicides
n
and pharmaceuticals. It reacts with acetic acid to form propyl acetate, with
ammonia to form propylamines and with halogens to form the ­corresponding
propyl halides.
Storage -Propanol can be stored in suitable containers at temperatures
n
below 40 °C and the exclusion of humidity for at least 1 year.
