Chemical process for the production of haloalkenone ethers
Abstract:
The present invention relates to a continuous process for producing a haloalkenone ether of the Formula (I) wherein R1 is C1-C6 haloalkyl, R2 is a C1-C6 alkyl or phenyl, the process comprising:—(i) reacting, in a first continuous stirred tank reactor comprising a solvent, a halide of Formula (II) wherein R1 is as previously defined and R3 is halogen, with a vinyl ether of Formula (III) wherein R2 is as previously defined, to form an intermediate compound of Formula (IV), wherein the concentration of the vinyl ether of Formula (III) in the reaction mass 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 the conditions within the subsequent reactor permit the elimination of hydrogen halide (HR3) from the intermediate compound of Formula (IV) to provide the haloalkenone ether of Formula (I).
