    摘要: There is disclosed a novel process for preparing products of the reaction of elemental phosphorus and elemental sulfur under reaction conditions wherein the phosphorus and sulfur are combined in a pre-mix at temperatures below the reaction temperature. The pre-mix may contain a diluent which is preferably the product of the reaction. Phosphorus pentasulfide can be prepared by heating the pre-mix to reaction temperatures wherein lower exotherm temperatures and reduced vibration are observed.

    摘要: The present invention is directed to the preparation of certain phosphorothioates and phosphonoates by means of a process which employs a three-phase system for the reaction of an alkali metal or alkaline earth metal phenate, pyridinate or pyrimidinate with a phosphorochloridothioate or phosphorochloridate under alkaline conditions and in the presence of tertiary amine and quarternary ammonium salt co-catalyst, but in the absence of both a hydrocarbon or chlorinated hydrocarbon solvent and a surfactant.
