摘　　要：利用新型泵式沸点仪,建立了一套恒压装置,在101.3kPa下测定了甲醇-甲基三甲氧基硅烷二元体系的汽液平衡数据,同时测定了甲基三甲氧基硅烷不同温度下的饱和蒸汽压,回归了它的Antoine常数,并对甲基三甲氧基硅烷的临界性质进行了估算。用Wilson、NRTL、Margules、VanLaar方程分别对所测数据进行了关联,结果良好。Isobaric vapour-liquid equilibrium data of methanol+methyltrimthoxysilane binary system were determined at 101.3 KPa with a new type of magnetically pump-ebulliometer.The saturated vapour pressure of methyltrimethoxysilane was measured at the same time.The constant A,B,C of Antoine was also obtained.The experimental data were correlated with the Margules,Van Laar,Wilson,and NRTL equations,the results were satisfactory.
