Patent ID: 8552222

Claim:
A continuous process for producing a haloalkenone ether of Formula (I): wherein R 1 is a C 1 -C 6 haloalkyl, and R 2 is a C 1 -C 6 alkyl or phenyl, the process comprising: (i) reacting, in a first continuous stirred tank reactor comprising a solvent, a halide of Formula (II): wherein R 3 is a halogen, with a vinyl ether of Formula (III): to form an intermediate compound of Formula (IV): wherein a concentration of the vinyl ether of Formula (III) in a reaction mass of said reacting step is 15% or less w/w; and (ii) transferring the reaction mass from the first continuous stirred tank reactor into a subsequent continuous stirred tank reactor, wherein conditions within the subsequent reactor permit elimination of hydrogen halide (HR 3 ) from the intermediate compound of Formula (IV) to provide the haloalkenone ether of Formula (I).
