摘　　要：BST型固体超强酸(TiO2/SO42-)催化合成萘乙酸甲酯最佳反应条件为:n(甲醇):n(α-萘乙酸)=10:1,反应温度65℃,反应时间2h,催化剂用量为α-萘乙酸质量的1%。酯收率大于92%。ethyl α - naphthylacetate is catalyzed by solid superacid (TiO2/SO42- ). The methanol to α -naphthylacetic acid is 10:1, reaction temperature 65 ℃, reaction time is 2 hours and the amount of catalysts is 1 % (based on the mass of α - naphthylacetic acid). under these conditions the yield of methyl α - naphthylacetate is over 92 % by GC analysis.
