甲基三氯硅烷——甲基三乙氧基硅烷二元体系等压汽液平衡研究

STUDY ON ISOBARIC VAPOR-LIQUID EQUILIBRIUM FOR ETHYLTRICHLOROSILANE + TRIETHOXYMETHYLSILANE BINARY SYSTEM

利用新型泵式沸点仪 ,在 10 1.3kPa下测定了甲基三氯硅烷—甲基三乙氧基硅烷二元体系汽液平衡数据 ,对甲基三乙氧基硅烷的临界性质进行了估算 ,分别用Wilson ,NRTL ,Margules ,VanLaar四种模型对所测数据进行了关联 。

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