摘要
以氨基磺酸为催化剂,用乙酸酐和β-萘酚合成了乙酸β萘酯.最佳条件为:乙酸酐6 mL(0.06 mol),β-萘酚7.2 g(0.05 mol),氨基磺酸1.0 g,反应温度80℃,反应时间30 min,产率达97.8%.反应时间短,催化剂可重复利用4次以上.
β-Naphthyl aceate was synthesized with acetic anhydride and naphthol using aminosulfonic acid as catalyst. The yield of βnaphthyl acetate was 97.8% under the optimum conditions： β-naphthlol 7.2 g（0.05 mol）, acetic anhydride 6 mL（0.06 mol）, aminosulfonic acid 1.0 g, reaction time 30 min, 80℃. The reaction time was short and the catalyst could be recovered and reused for more than 4 times.
