Vapor-Liquid Equilibrium Data for Binary Systems, Aceton-Methyl Acetate, Acetate-Carbon Tetrachloride, Butyl Acetate and Cyclohexane-Butyl Acetate

Isobaric vapor-liquid equilibrium data are presented for four binary systems. Analysis of experimental data show that benzene-butyl acetate mixtures form nearly ideal solution and the other binary mixtures behave nonideally. The Redlich-Kister equations were used to correlate the experimental data with good accuracy. Binary vapor-liquid equilibrium data at atmospheric pressure were determined for the mixtures of acetone, methyl acetate, benzene, carbon tetrachloride, butyl acetate, and cyclohexane using a Colburn still. Anazeotrope was discovered for the acetone-methyl acetate system. The ordinary and modified Redich-Kister equa­tions were found to represent the equilibrium data well.
