A process for removing residual acidic chlorine from acyloxysilanes, comprising:
- reacting a metal carboxylate with a composition comprising an acyloxysilane and acidic chlorine, to form a metal chloride.
A process for producing acyloxysilane, comprising:
- reacting an organochlorosilane with a carboxylic acid or a carboxylic anhydride, to form a composition comprising an acyloxysilane and acidic chlorine;
- reacting a metal carboxylate with said composition, to form a metal chloride;
- and
- separating off said metal chloride from said composition.
In a process for producing acyloxysilane, including the step of reacting an organochlorosilane with a carboxylic acid or a carboxylic anhydride to form a composition comprising said acyloxysilane and acidic chlorine, the improvement comprising further reacting a metal carboxylate with said composition to reduce the amount of said acidic chlorine present in said composition.
