Abstract:Chlorotrimethylsilane was an important reagent of organosilicone,playing great part in chromatogram, organic Synthesis, protection of group and so on.This article was about the synthysis of chlorotrimethylsilane by hexemethyl disiloxane from industrial recycling(with 43.2% of toluene). And in the article,. chlorination reagent such as PCl5, SOCl2 and HCl, temperature, time and catalyst such as FeCl3, CaCl2 and ZnCl2 was tested. As the result showed, the best condition was with hydrogen chloride as chlorination reagent, FeCl3 as catalyst and reacting for 8 hours, and the yield of TMCS was about 91.3%, As the GC tested, the purity of chlorotrimethylsilane was 99.5%.
