摘要

用自吸循环高压平衡釜，测定了乙醛-二醋酸亚乙酯、醋酸-二醋酸亚乙酯、乙醛-醋酐、醋酸乙烯-二醋酸亚乙酯、醋酸乙烯-醋酐5组二元体系的恒温汽液平衡数据．对缔合体系的汽相采用“化学理论”修正其非理想性，采用UNIQUAC方程对液相的非理想性进行修正．计算结果令人满意．

Abstract

The vapor-liquid data were measured for the isotherm of binary systems of aldehydeethylidene diacetate

acetic acid-ethylidene diacetate

aldehyde-acetic anhydride

vinyl acetate ethylidene diacetate and vinyl acetate-acetic anhydride

with a self-suction equilibrium still.The“chemical theory”was used to correct the nonideality of the vapor phase with associated molecules.UNIQUAC equation was used to calculate liquid activity coefficient.The calculated results of the thermodynamic model show good agreement with experimental data.
