甲醇—乙烯基三甲氧基硅烷二元体系等压汽液平衡研究

Study on Isobaric Vapor-Liquid Equilibrium for Methanol+Vinyltrimethoxysilane Binary System

采用新型泵式沸点仪,在101.3kPa下测定了甲醇—乙烯基三甲氧基硅烷二元体系等压汽液相平衡数据,并对乙烯基三甲氧基硅烷的临界性质进行了估算,分别用Wilson,NRTL,Margules,VanLaar四种模型进行了关联,结果令人满意。

Isobaric vapor-liquid equilibrium data of methanol+vinyltrimethoxysilane binary system was determined at 101.3 kPa with a new type of magnetically pump-ebulliometer. At the same time, the saturated vapor pressure of vinyltrimethoxysilane was measured. The experimental data was correlated with the Wilson, NRTL, Margules and Van Laar equations and the results were satisfactory.
