Abstract:
1. A process for preparation of an alkoxysilane represented by the formula: wherein n is from 0 to about 2; and wherein each R is independently selected from the group consisting of: a linear, branched or cyclic alkyl of having 1 to 12 carbon atoms, aryl, and acyl, wherein at least one of said alkyl, aryl and acyl groups is optionally substituted by at least one alkyl, alkoxy, halo, cyano or aryl; said process comprising the step of: contacting elemental silicon and an hydroxy compound represented by the formula: wherein R is selected from the group consisting of: a linear, branched or cyclic alkyl having 1 to 12 carbon atoms, aryl, and acyl, wherein at least one of said alkyl, aryl and acyl groups is optionally substituted by at least one alkyl, alkoxy, halo, cyano or aryl; wherein said contacting is carried out in the presence of at least one catalyst selected from the group consisting of: copper, zinc, and nickel; and a non-ionizing radiation selected from the group consisting of: microwave, radio frequency (RF), and a combination thereof, and at a temperature, pressure, and time sufficient to form said alkoxysilane.
