    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).

    Abstract translation: 本发明涉及制备式（I）的卤代烯酮醚的连续方法，其中R 1为C 1 -C 6卤代烷基，R 2为C 1 -C 6烷基或苯基，所述方法包括： - （i） （III）的乙烯基醚（其中R 2如前所定义）反应，形成式（II）的卤化物，其中R 1如前定义且R 3为卤素，形成式 IV），其中式（III）的乙烯基醚在反应物中的浓度为15％或更少w / w; 和（ii）将来自第一连续搅拌釜反应器的反应物料转移到随后的连续搅拌釜反应器中，其中后续反应器内的条件允许从式（IV）的中间体化合物中除去卤化氢（HR3）以提供 式（I）的卤代烯酮醚。
