HCID 12682TetramethoxysilaneYield 94,292.898%

Procedure

Example 2 was repeated except that 0.04 gram of rubidium formate was used as the alkali carboxylate catalyst component and reaction time was 4.0 hours. Under these conditions 5.2 grams of methyltrimethoxysilane; 44.0 grams of tetramethoxysilane were produced; and 14.0 grams of methanol was unreacted. Of the total organosilanes in the distillation product 10.5 percent was methyltrimethoxysilane.
