| Abstract：Trimethoxysilane was directly synthesized from silicon and methanol using cuprous choride as catalyst.The Si-Cu (2)Cl (2) mixture was pretreated by microwave piror to feeding methanol. Effect of microwave pretreatment power ,pretreatment time and different microwave pretreatment conditions on the rection was discussed.After the mixtue\[m(Si)∶m(Cu (2)Cl (2)) =10∶0.4\] was pretreated by microwave for 3 min at high power in N (2), the content of trimethoxysilane is 54.0% in the distillate. |
