METHOD OF PRODUCING A HYDROLYZABLE SILICON-CONTAINING COMPOUND

The present invention provides a safe, inexpensive, and high yield means of producing a hydrolyzable silicon-containing compound, e.g., an organooxysilane and the like. A compound (A) represented by the general formula R1-O-R2 wherein R1 represents a C4-30, substituted or unsubstituted, tertiary alkyl group or aralkyl group and R2 represents a C1-30, substituted or unsubstituted, monovalent hydrocarbyl group or acyl group, is reacted in the presence of a Lewis acid catalyst with a halosilane (B) represented by the general formula R3mSiX4-m wherein R3 represents the hydrogen atom or a C1-30 substituted or unsubstituted monovalent hydrocarbyl group, X is independently bromine or chlorine, and m represents an integer from 0 to 3.

Practical conversion of chlorosilanes into alkoxysilanes without generating HCl

Alcohol-free: A versatile, efficient, and practical synthesis of alkoxysilanes without generation of HCl involves the reaction of chlorosilanes with unsymmetrical ethers in the presence of a Lewis acid (see scheme). The reaction proceeds through selective cleavage of C-O bonds and is superior to conventional processes. Industrially feasible reagents are used and only one by-product results. Copyright

Process for the continuous preparation of acyloxysilanes

Acyloxysilanes are prepared by a process of reacting an organochlorosilane with an excess of monocarboxylic anhydride at elevated temperature, thereby forming product acyloxysilane and by-product acyl chloride transferring the reaction mixture to the middle inlet of a separation tower having a still pot at its base, removing excess carboxylic anhydride by distillation at the tower top under reduced pressure, removing acyl chloride by-product from the separation tower, uniformly removing acyloxysilane from the tower still pot, and reacting virtually quantitatively the residual acid chloride present in the acyloxysilane removed from the still pot by adding a metal carboxylate to the acyloxysilane and separating the metal chlorides formed from the product.

Method of preventing discoloration of vinylacetoxysilanes

Discoloration of vinylacetoxysilanes is prevented by adding thereto 25 to 500 ppm, based on the amount of vinylacetoxysilane, of 3,5-di-tert.-butylpyrocatechol, 2,6-di-tert.-butyl-4-methylphenol, 2-mercaptobenzimidazole or a mixture thereof.

Process for preparing triacetoxysilanes from tris(amino)silanes

Triacetoxysilanes are prepared by adding a tris(amino)silane to acetic anhydride and maintaining the reaction mix at a temperature no greater than about 50° C.
