摘要
报道了以３，５－二羟基苯甲酸为起始原料合成３，５－二羟基苯乙酮的方法，并讨论了其优惠工艺条件。该工艺流程短、成本低。总收率为４１％，原药纯度达到９８％，熔点１４４℃～１４６℃。
The method of synthesizing 3,5-dihydroxyacetophenone with 3,5-dihydroxybenzoic acid as starting material is reported,and the optimum synthesis conditions are discussed.This method was featured by shorter processing time and lower costing.The total yield is 41%,the purity of the product can reach 98%,and the melting point is 144℃～146℃。
