VAC-TB-H_2O三元系的相平衡—汽液、液液平衡数据的测定和关联

PHASE EQUILIBRIUM IN THE TERNARY SYSTEM VAC—TB—H_2O—DETERMINATION AND CORRELATION OF VLE AND LLE DATA

本研究以适用于部分互溶体系改良式Othmer釜测定了1atm下乙酸乙烯酯—甲基丙醇—水(VAC-TB-H_2O)体系的汽液和液液平衡数据,应用NRTL方程和多参数Wilson方程对平衡数据进行了关联。

Isobaric vapor-liquid equilibrium and liquid-liquid equilibriumdata at 760 mmHg for a ternary system of vinyl acetate-Methylpropanol-water have been determined in a modified Othmerstill.By using NRTL and modified multiparameter Wilson equation,the predicted ternary phase equilibria data are in good agreementwith the experimental results.The parameters in the above equationare wholly provided from corresponding binary systems.
