专利汇可以提供Process for preparing alkyl or aryl phosphorus halides and mixed isomers thereof专利检索，专利查询，专利分析的服务。并且Alkyl or aryl phosphonic or phosphonothioic dihalides and phosphinic or phosphinothioic monohalides are prepared by reacting an alkyl halide or aryl halide respectively with a trivalent phosphorus compound having at least two halogens attached thereto, and preferably three halogens such as phosphorus trihalide, in the presence of P4O10 or P4S10 under at least autogenous pressure at a temperature of from 200*C. to 450*C. The compounds obtained are useful as constituents in insecticides, fungicides, pharmaceuticals, and as intermediates in preparation of other organophosphorus compounds.，下面是Process for preparing alkyl or aryl phosphorus halides and mixed isomers thereof专利的具体信息内容。
