Abstract

A process for the manufacture of an alkenone comprising the steps of: (a) providing a halogenated precursor of the alkenone and (b) subjecting at least a fraction of the halogenated precursor of step (a) to a thermolysis reaction to form a reaction mixture comprising the alkenone and a hydrogen halide wherein the hydrogen halide is removed from the reaction mixture by cyclonic separation is described.
