A study of the mechanism of the decomposition of tetrachlorodimethyldisilane via the catalysis of AlCl3(AlCl3催化裂解二甲基四氯二硅烷的理论计算)

用密度泛函(B3L YP)方法及二级微扰(MP2)方法对二甲基四氯二硅烷的裂解机理进行了研究.计算结果表明,裂解分三步进行:第一步为吸热反应,第二、三步为放热反应;反应的焓变分别为:ΔH1(67.484 kJ •mol-1), ΔH2(- 232.546 kJ •mol-1), ΔH3(- 117.347 kJ •mol-1).三步反应的活化能表明反应较易进行.反应的速控步是第三步,其正反应的活化能(Ea3)为152.552 kJ •mol-1....
