Abstract
A process for the production of ketene dimers from fatty acid halides by reaction with tertiary amines. The process is operated batchwise and the reaction is started in the presence of an initial reaction mixture containing ketene dimer and pre-prepared crystals of tertiary amine hydrogen halide and is carried out in the substantial absence of additional solvents.
