    • 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).
    • 本发明涉及制备式(I)的卤代烯酮醚的连续方法,其中R 1是C 1 -C 6卤代烷基,R 2是C 1 -C 6烷基或苯基,该方法包括:(ⅰ) 连续搅拌釜反应器,其包含溶剂,式(II)的卤化物,其中R 1如前所定义且R 3是卤素,与式(III)的乙烯基醚(其中R 2如前所定义)形成中间体式 IV),其中反应物质中式(III)的乙烯基醚的浓度为w / w为15%以下; 和(ii)将反应物质从第一连续搅拌釜反应器转移到随后的连续搅拌釜反应器中,其中随后反应器中的条件允许从式(IV)的中间体化合物除去卤化氢(HR 3),以提供 式(I)的卤代烯酮醚。
