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%. 目 录 三甲基氯硅烷的合成相关范文 |
