发明名称 Process for the manufacture of alkyl ketene dimers by dimerization with tertiary amines.
摘要 A process is disclosed for the synthesis of alkyl ketene dimers by the dehydrohalogenation of a C6 - C22 saturated or unsaturated linear fatty acid halide, comprising reacting the fatty acid chloride with a cyclic tertiary amine in an inert solvent at a temperature of up to 75 DEG , separating tertiary amine hydrochloride salts from alkyl ketene dimer dissolved in the solvent, and recovering the alkyl ketene dimer from the solvent.
