Preparation method of salicylate

The invention relates to a preparation method of salicylate, and belongs to the technical field of chemical engineering, the method comprises the following steps: S1, uniformly mixing and stirring methyl salicylate, alcohol and a catalyst, and reacting for 5-10 hours at the temperature of 130-190 DEG C; wherein the molar ratio of the methyl salicylate to the alcohol is 1: (1.7-2.0); the catalyst adopts a Sn-Rh-La-Mg-Na-K/dolomite catalyst, and the use amount of the Sn-Rh-La-Mg-Na-K/dolomite catalyst is 0.1 to 0.5 percent of the total mass of the methyl salicylate and the alcohol; and S2, filtering the product obtained in the step S1 to remove the catalyst, washing with water, then carrying out reduced pressure distillation under the pressure of 0.93-1.8 kPa, and collecting fractions to obtain the product. The preparation method disclosed by the invention has the effects of being simple in process, relatively high in product yield, relatively high in purity and good in product fragrance. 本申请涉及一种水杨酸酯的制备方法，属于化工技
