二烷氧基硅烷-乙烯基三甲氧基硅烷组成的二元体系的密度与折光率研究

摘要

常压下测定了二甲基二甲氧基硅烷、二甲基二乙氧基硅烷、甲基乙烯基二乙氧基硅烷与乙烯基三甲氧基硅烷这3个二元体系在298.15K、303.15K、308.15K、313.15K及318.15K下的密度和折光率,建立了这3个二元混合体系的密度与组成和温度关系的计算方程.%The density and refractive index were determined for three binary mixtures of ethenyltrimethoxysilane with dimethyldimethoxysilane,dimethyldiethoxylsilane,and methylvinyldiethoxysilane at T=(298.15,303.15,308.15,313.15 and 318.15) K and atmospheric pressure using a DMA4500/RXA170 combined system.The calculation equations of three binary mixtures' density and composition related with temperature were established.
