Abstract
A continuous method is provided for making a mixture of alkylpolyacyloxysilane and alkoxyacyloxysilane which is useful as a curing catalyst for a one part moisture curable silicone RTV. A steady-state mixture of alkylpolyacyloxysilane and alkoxyacyloxysilane is established in the reboiler of a distillation system having a reboiler, a distillation column, and a condenser as a result of the continuous introduction into the distillation column of a mixture of an alkyltrichlorosilane and silicon tetrachloride and the direct feeding of an alcohol such as tertiary butanol into the reboiler. A mixture comprising alkylpolyacyloxysilane and alkoxyacyloxysilane and aliphatic carboxylic is continuously pumped to a collection vessel. The continuous stripping and recycling of the aliphatic carboxylic from the collection vessel results in the continuous production of the desired silane mixture.
