摘　　要：利用新型泵式沸点仪,在 101. 3kPa下测定了乙烯基三氯硅烷—乙烯基三甲氧基硅烷二元体系汽液相平衡的数据,用间接法推算了与之平衡的气相组成,并用基团贡献法计算了乙烯基三甲氧基硅烷的临界参数和偏心因子,分别用Wilson、NRTL、Margules、VanLaar四种模型进行了关联,结果令人满意,拟合精度可以满足工程设计的要求.Isobaric vapor-liquid equilibrium data of vinyltrichlorosilane + vinyltrimethoxysilane binary system was determined at 101.3kPa with a new type of magnetical 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.
