    摘要: A pollution-free process for forming trialkyl phosphite by reaction of phosphorus trichloride with alcohol in the presence of a tertiary amine acid acceptor is described in which by-product hydrochloride salt of the acid acceptor is electrolyzed to regenerate the tertiary amine for recycle for further use in reacting additional phosphorus trichloride with alcohol to form additional trialkyl phosphite product.

    摘要: Ferric chloride contained in liquid waste streams comprising higher boiling chlorinated hydrocarbons may be substantially reduced by contacting the waste stream with an amount of water sufficient to convert a substantial amount of the ferric chloride in said stream to solid ferric chloride hexahydrate, and then removing the solid hexahydrate from the waste stream for instance by filtration.
