Preparation method of fluoroglycofen-ethyl

The invention discloses a preparation method of fluoroglycofen-ethyl. The preparation method comprises the following steps: mixing acifluorfen, toluene and a catalyst, and heating to 30-60 DEG C; adding potassium carbonate into the heated mixture, and continuously heating to 45-70 DEG C; adding ethyl chloroacetate into the heated mixture, and continuously heating to 90-105 DEG C for reaction; after the reaction is finished and a reactant is slowly cooled, extracting by adopting a mixed solution of toluene and water, and collecting an organic layer; and distilling the organic layer until no fraction exists, and thus obtaining the fluoroglycofen-ethyl. The yield of fluoroglycofen-ethyl prepared through the preparation method is high, the content of the prepared fluoroglycofen-ethyl is high, specifically, the yield reaches 95% or above, and the content reaches 73% or above; and in addition, the preparation process has the advantages of fewer by-products, simplicity in operation, shorter required time and higher production efficiency.
