摘要

本文测定了以乙醇、丙酮、正己烷组成的3组二元体系和1组三元体系以及环己烷、异丙醇、乙酸乙酯、丁酮所组成的3组三元体系在101.3～902.OkPa压力下的加压共沸点．根据有关二元共沸数据对在相同压力下的三元体系进行了预测，预测值与实测值符合良好．

Abstract

The azeotropic data were determined for four ternary systems of ethanol-acetone-n-hexane

cyclohexane-ethyl acetate-isopropanol

cyclohexane-ethyl acetate-bu-tanone

cyclohexane-isopropanol-butanone and three binary systems of ethanol-acetone

ethanol-n-hexaneacetone-n-hexane at the pressures from 101.3 to 911.O kPa.The variation of binary azeotropes with pressure were studied.The ternary azeotroplc data were predicted by Wilson equation on the basis of corresponding binary azeotropic data at the same pressures.The predicted values are in good agreement with the experimental data.
