“…[3][4][5] The level of industrial silicon is determined by the production of its monomer, in which dichlorodimethylsilane ((CH 3 ) 2 SiCl 2 , M 2 ) is the largest and most versatile organic silicon monomer. 6,7 At present, the dichlorodimethylsilane is prepared from direct synthesis method. 8 But this method will accumulate a lot of waste, such as methyltrichlorosilane (CH 3 SiCl 3 , M 1 ) and trimethylchlorosilane ((CH 3 ) 3 SiCl, M 3 ).…”

Organosilicon material is widely used because of its dual structure. Dimethyldichlorosilane is the largest and most versatile of organic silicon monomer. In this article, MP2/6-311 + + G (3df, 2pd) basis set has been used to calculate the reaction mechanism of disproportionation for producing dimethyldichlorosilane by catalysts AlCl 3 /ZSM-5 (3T, 4T, 6T). The results show that the activation energies (3T, 4T, 6T) of the ratedetermining step of the main reaction are: 100.3, 110.6 and 113.1 kJ mol −1 , respectively. The structure analysis, activation energy analysis and LOL analysis for different catalysts all show that the catalytic effect of 4T cluster AlCl 3 /ZSM-5 is the best.
