STUDY ON THE LIQUID-LIQUID EQUILIBRIUM OF METHYL ACETATE-METHANOL-WATER-ACETIC ACID SYSTEM

摘要

LLE (liquid-liquid equilibrium) data have been determined in the LLE still for the quaternary system of methyl acetate-methanol-water-acetic acid at 20°C,30°C,40°C and 50°C under atmospheric pressure. These works can provide sufficient data support for industry design and add new LLE data into the data bank. According to the model parameters correlated by the activity coefficient models including NRTL and UNIQUAC, LLE data of the quaternary system were predicted by simplex optimization and the comparison between calculated and experimental data shows good agreement.
