Preparation method of cyhalofop-butyl

The invention provides a preparation method of cyhalofop-butyl. The preparation method comprises the following steps of: (1) taking 3, 4-difluorobenzonitrile and (R)-2-(4-hydroxyphenoxy) propionic acid as raw materials, carrying out an etherification reaction in the presence of an acid-binding agent potassium carbonate and a water-carrying agent, and filtering to remove potassium fluoride, so as to obtain potassium salt as shown in a formula I: (2) acidifying the potassium salt as shown in the formula I, so as to obtain an acidified product; and (3) carrying out an esterification reaction on the acidification reaction product obtained in the step (2) and n-butyl alcohol to obtain cyhalofop-butyl. According to the preparation method, the problems that in the prior art, mixed salt cannot beseparated, many three wastes are generated, COD and ammonia nitrogen in wastewater are high, and the productivity cannot be improved are solved, resource utilization of by-products is achieved, the product yield is high, and continuous and large-scale production of cyhalofop-butyl is conveniently achieved.
