Abstract: A continuous process for the preparation of maleic anhydride from an aqueous solution of maleic acid formed in the production of maleic anhydride by the catalytic oxidation of aliphatic or aromatic hydrocarbons, with the continuous elimination of the impurities which accompany this maleic acid solution or which are subsequently formed in the course of the conversion of maleic acid into maleic anhydride.
Abstract: Tetrachloropyridine is prepared by heating pentachloropyridine in an aqueous medium under pressure, with agitation, in the presence of a particulate oxidizable metal, e.g., zinc and a hydrogen-producing acid, e.g., hydrogen chloride. The tetrachloropyridine is then conveniently extracted with an inert, water-immiscible solvent, e.g., a halogenated hydrocarbon.
