一甲基三氯硅烷与三甲基氯硅烷的歧化反应可以制备最重要的单体二甲基二氯硅烷，采用B3LYP/6-311++G(3df,2pd)方法对LiAlCl4/γ-Al2O3催化剂体系进行了计算，得到其主反应速控步的活化能为15.59 kJ·mol-1;实验表明LiAlCl4/γ-Al2O3催化制备二甲的最高产率为81.3%，比γ-Al2O3的产率高，结果与计算匹配.

-
Most important monomer dimethyldichorosilane could be prepared by disproportionating methyltrichlorosilane and chlorotrimethysilane. Disproportionation catalyzed by LiAlCl4/γ-Al2O3 were calculated at B3LYP/6-311++G(3df,2pd) level. Activation energies of the rate-determinning step of main reaction was 15.59 kJ·mol-1. The experiment indicated the producticity that LiAlCl4/γ-Al2O3 catalyst preparing dimethyldichorosilance is 81.3%. It was higher than γ-Al2O3catalyst, and it coincided with calculated results.
