Abstract: A method for preparing a phenoxycarboxylate includes 1) allowing a salt of a phenolic compound and a halogenated carboxylate to subject to a condensation reaction in a polar solvent under the action of a catalyst; and 2) adding an acid-containing organic solvent to the condensation reaction liquid in step 1) to perform an acidification, and purifying the precipitated halogenated inorganic salt to obtain a phenoxycarboxylate. A catalyst is added in the condensation process, which can improve the reaction rate, achieve the reaction at room temperature and high material conversion rate, and avoid the problem in the prior art that the reaction needs to be performed at high temperature, about 120° C. After the condensation reaction is completed, the salt is removed by dry filtration (an anhydrous condition) by adding a methanol hydrogen chloride solution. There is no industrial wastewater, raw materials are easily recycled, and the reaction yield is high.
