甲基三氯硅烷-二甲基二氯硅烷-苯体系中二元体系的汽液平衡数据推算

在预测卤化硅烷体系性能时,通过改变溶液的混合规则来确定预测方案。估算了甲基三氯硅烷、二甲基二氯硅烷、苯相互之间组成的二元体系在恒压101.325 kPa下的相互作用参数,这种估算是基于把汽相看成理想溶液来实现的,而且采用matlab优化工具箱中的非线性最小二乘法用Wison模型关联了实验数据,预测结果比文献更逼近实验数据。这些二元体系汽液平衡数据为卤硅烷的生产提供了理论依据。

Calculation of binary mixtures VLE data for methyltrichlorosilane-dimethyldichlorosilane-benzene

Prediction of the phase behavior of systems containing halogenated silanes requires modification of the mixing rules used for solution models. In this work, interaction parameters of binary systems of methyltrichlorosilane and dimethyldichlorosilane and benzene at 101.325 kPa are calculated under condition of looking vapor phase as ideal liquid. Moreover, the experimental data are corrected with the Wilson equation by non-linear least square method of Matlab optimization toolbox. And the prediction values obtained by Wilson model in this work are much closer to the experimental values than the literature. The VLE of binary systems provides essential theory for the production of the halogenated silane.
