摘要
以氯化氢为裂解助剂,N,N-二丁基-1-丁胺为催化剂,分析了1,1,2-三氯-1,2,2-三甲基二硅烷的催化裂解机理。在其亲核取代反应中,氯化氢与N,N-二丁基-1-丁胺结合生成了亲核能力更强的N,N-二丁基-1-丁胺盐酸盐,进而提高了催化裂解效率。通过上述催化裂解反应,可有效将二硅烷转化为经济价值较高的二甲基二氯硅烷等单体。
The catalytic cracking mechanism of 1,1,2-trichloro-1,2,2-trimethyldisilane was analyzed with hydrogen chloride as cracking additives and N,N-dibutyl-1-butylamine as catalyst.In the reaction of nucleophilic substitution,hydrogen chloride combined with N,N-dibutyl-1-butylamine to form N,N-dibutyl-1-butylamine hydrochloride with stronger nucleophilicity,which improved the catalytic cracking efficiency.The disilane can be effectively converted into monomeric silane such as dimethyldichlorosilane with higher economic value by the catalytic cracking.
