摘　　要：介绍了甲基氯硅烷合成中的副产共沸物[SiCl4(CH3)3SiCl]的主要分离方法:恒沸精馏法和酯化分离法,并分述了共沸物分离后三甲基氯硅烷和四氯化硅的深加工方法。三甲基氯硅烷可用来制备六甲基二硅氧烷、六甲基二硅氮烷、六甲基二硅烷等;四氯化硅可用来制备四丁酮肟基硅烷、四乙酰氧基硅烷、正硅酸乙酯及其缩聚物、烧制气相法白炭黑等。The main methods for the separation of azeotrope SiCl4(CH3)3SiCl in the synthesis of methyl chlorsilane,which were constant boiling rectification and esterifying sepraration.The deep-processing of trimethylchlorosilane and tetrachlorosilane was also introduced.Trimethylchlorosilane could be prepared as(CH_3)_6Si_2O,(CH_3)_3SiNHSi(CH_3)_3 and(CH_3)_3SiSi(CH_3)_3,and so forth.Tetrachlorosilane could be prepared as tetra(methyl ethyl ketoxime)silane,tetra triacetoxysilane,tetraethylorthosilicate and its polycondensate,and made fumed silica.
