Description

Description générale

Propyl acetate (n-propyl acetate) is the propyl ester of acetic acid. The absolute rate constant for the reaction of n-propyl acetate with OH radicals has been reported to be (k × 10^-9lmole^-1s^-1) = 2.6 ± 0.5lmole^-1s^-1. Liquid-liquid equilibrium of the ternary system composed of water, acetic acid and propyl acetate has been investigated at various temperatures (298.15, 313.15 and 363.15K). Experimental values were found to be in close agreement with that of UNIQUAC (UNIversal QUAsiChemical) model. It has been identified as one of the volatile ester produced from Penicillium commune.

Application

Propyl acetate may be employed as a solvent for the evaluation of vapor pressure of the polymeric solution of polystyrene. It may be used in the preparation of geranyl acetate.
