Claims19
A process for producing trialkoxysilane of the formula HSi(OR).sub.3 wherein R is an alkyl group containing from 1 to 6 carbon atoms which comprises:
- (a) forming a reaction mixture comprising an alcohol of the formula ROH wherein R is as defined above, an inert solvent, silicon metal, and a catalytically effective amount of copper (II) hydroxide;
- and
- (b) reacting said alcohol with said silicon metal in the presence of said copper (II) hydroxide to produce the trialkoxysilane.
A process for producing trimethoxysilane, HSi(OCH.sub.3).sub.3, which comprises:
- (a) forming a reaction mixture comprising methanol, an inert solvent, silicon metal and a catalytically effective amount of copper(II) hydroxide;
- and
- (b) reacting said methanol with said silicon metal in the presence of the copper (II) hydroxide to produce trimethoxysilane.
