| 摘要 |
A process is disclosed for the synthesis of alkyl ketene dimers by the dehydrohalogenation of a C8-C22 saturated or unsaturated linear fatty acid halide, comprising reacting the fatty acid chloride with a cyclic tertiary amine in a solvent that is selected from the group consisting of cycloalkanes and alkanes at a temperature of up to 75 DEG , mechanically separating tertiary amine hydrochloride salts from alkyl ketene dimer dissolved in the solvent, and recovering the alkyl ketene dimer from the solvent.
