摘要： 本文使用自行设计的带机械搅拌器的平衡釜,在760mmHg压力下,测定了乙酸乙酯-水二元部份互溶物系的汽、液平衡数据.经热力学检验,该数据符合热力学一致性.用NRTL等13个活度系数方程进行热力学关联和计算,获得了满意的结果,尤以McCann方程和NRTL方程拟合的精度最佳.

Abstract: The isobaric Vapor-Liquid equilibrium data at 760 mmHg of binary system for ethyl acetate and water have been determined by a self-designed equilibrium still and tested to be in keeping with thermodynamic consistency by Herrington empirical method. Compared with the values calculated by 13 correlated equations of activity coefficient, the data are fairly satisfactory, in particular, the imitation accuracy of the values obtained by McCann equation are the best.
