Synthesis and properties of functionalized alkylalkoxysilanes

A method of chloroalkylalkoxysilanes synthesis scalable to pilot production has been proposed. Morpholinotrialkoxysilanes have been prepared and studied as vulcanizing agents for low-molecular silicone rubbers. The reaction of N-morpholinomethyltrialkoxysilanes with triethanolamine has afforded N-[(silatranyl)-methyl]morpholine; it has been studied by X-ray analysis.

METHOD FOR PREPARATION OF ALKOXYSILANES HAVING REDUCED HALIDE CONTENT

Disclosed is a method for lowering the residual halide content in alkoxysilanes. The method comprises contacting the alkoxysilane having residual halide content with activated carbon followed by separation of the alkoxysilane. The resultant materials are useful as intermediates for the preparation of other chemical compounds and for use in electronics applications.
