[Also in Division C3] Organotin stabilizers for P.V.C. are prepared by reacting (a) an organotin halide RSnHal 3 , where R is a hydrocarbon group of up to 20 carbons, with an equivalent amount (based on halogen) of a mixture of (b) alkali metal sulphide, (c) an alkali metal salt of a carboxylic acid of up to 20 carbons and (d) an alkali metal hydroxide in an amount of 2 moles per mole of carboxylate group; the product is a mixture of (RSnS 1.5 )n and a mixed anhydride of RSnOOH and the carboxylic acid. Examples employ (a) butyl tin trichloride, (b) sodium sulphide and (c) sodium salts of laevulinic, adipic, maleic, sebacic, phthalic, and citric acids or potassium salts of oleic, stearic or ricinoleic acids with (d) sodium or potassium hydroxide.
