Abstract:
The invention provides a direct solvent free method for the selective synthesis of trialkoxysilanes having the formula SiH(OR) 3 , the method comprises providing a mixture of metallic silicon and copper based catalyst in a packed bed reactor, wherein neither the metallic silicon nor the silicon-catalyst mixture is subjected to any washing step. Claim  1  relates to a direct solvent free method for the selective synthesis of trialkoxysilanes having the formula SiH(OR) 3 , wherein each R is a C 1 -C 4  alkyl, the method comprising the steps of: providing a mixture of metallic silicon and copper based catalyst in a packed bed reactor; heating the mixture at an activation temperature of about 180° C.-about 250° C.; introducing C 1 -C 4  alcohol to the reactor at a reaction temperature of about 180° C.-less than about 250° C.; condensing the reaction products in a heat exchanger; and collecting the condensed reaction products, wherein neither the metallic silicon nor the silicon-catalyst mixture is subjected to any washing step, including a hydro fluoric acid (HF) washing step.

Claim (Index 5):
The method according to  claim 1 , wherein the copper based catalyst is selected from the group consisting of copper (I) chloride, copper (II) hydroxide, copper (II) oxide, and mixtures thereof.
