Process for the production of alkoxysilanes of the formula HSi(OR) , where R is an alkyl group containing 1 to 6 carbon atoms, and/or alkyl orthosilicates of the formula Si(OR) , where R is an alkyl group containing 1 to 6 carbon atoms. In a preferred embodiment, the process comprises reacting silicon metal with an alcohol in a suitable solvent in the presence of a cupric bis(diorganophosphate) catalyst. A polymeric form of ethyl orthosilicate, a by-product of the reaction, is the preferred solvent. The production of triethoxysilane and tetraethyl orthosilicate is preferred, with triethoxysilane being particularly preferred.

Process for the manufacture of alkoxysilanes and alkoxy orthosilicates

Leaks in a vessel or pipe line and the like adapted for containing a fluid re sealed by means of a polymerization system comprising a catalytically polymerizable organic monomer and a polymerization catalyst therefor, by first providing a catalytically effective amount of the catalyst at the situs of the leak and then supplying vapor of the monomer to the interior of the vessel under sufficient pressure and for a sufficient period of time to permit contact thereof with the catalyst to effect formation of a polymer providing a solid seal at the situs of the leak.
