摘要
本文实例了乙醇－环己烷、乙醇－乙酸乙酯、乙醇－丁酮、异丙醇－正己烷、丙酮－环己烷五组二元体系在１０１．３～９１１．０ｋＰａ压力下的加压共沸数据。研究了二元共沸点随压力变化的规律。并用ＵＮＩＦＡＣ基团贡献法预测了这五组二元体系在相应压力下的共沸数据，与实测值作了比较，两者符合良好。
The azeotropic data of five binary systems,namely,ethanol-cyclohexane、ethanolethyl acetate、ethanol-butanone、isopropanol-hexane、acetone-cyclohexane,at pressures of up to 911.0 kPa,were determined.Variation of the binary azeotropic point with pressure was studied.Corresponding azeotropic data were predicted by the UNIFAC method at the same pressure.The predicted data were in a good agreement with the experimental data.
