    摘要: Process for the production of alkoxysilanes of the formula HSi(OR)3, where R is an alkyl group containing 1 to 6 carbon atoms, and/or alkyl orthosilicates of the formula Si(OR)4, 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.

    摘要: Leaks in a vessel or pipe line and the like adapted for containing a fluidre 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.
