Vapor-Liquid Equilibria of a Minute Amount of Ethyl Caproate Isoamyl Acetate and 1-Propanol in Aqueous Ethanol Solution under Reduced Pressure

Abstract

Vapor-liquid equilibria of aqueous ethanol solutions containing a very small amount of ethyl caproate, isoamyl acetate and 1-propanol were determined using an Othmer-type still at 66.7 kPa. The equilibrium ratio of the minor components increases with decreasing mole fraction of ethanol in the solutions. The results were correlated with the NRTL equation.
