摘　　要：以苯酐和-α萘酚为原料,在B2O3催化下合成了2-[(1-羟基-2-萘基)羰基]苯甲酸,反应的优化条件为:n(B2O3)∶n(苯酐)∶n(-α萘酚)=1.5∶1.5∶1,反应温度为180￣190℃,反应时间为2.0h,收率达97.8%,并通过元素分析、1H NMR、IR、EIMS对产物结构进行了表征。2-[ （1-Hydroxy-2-naphthyl）carbonyl] carbonyl] benzoic acid was prepared from phthalic anhydride and α-naphthol using boric oxide as a catalyst. The optimal reaction conditions were as follows： the molar ratio of boric oxide, anhydride and α-naphthol =1.5 ： 1.5 ： 1, reaction temperature 180-190℃ and reaction time 2.0 h, the yield reached 97.8%. The obtained product was characterized by element analysis, ^1H NMR, IR and EIMS.
