| Abstract: | 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. |
