摘要
以氯化铯为催化剂,以乙酸酐和β-萘酚合成了乙酸-β-萘酯。确定了最佳反应条件为:乙酸酐与β-萘酚的摩尔比1.3∶1、氯化铯用量0.5g、反应温度80℃、反应时间40min,在此条件下,乙酸-β-萘酯产率达94.7%。催化剂重复使用5次,仍保持较高的催化活性。
Abstract: β-Naphthyl acetate was synthesized with as catalyst. The yield of β-naphthyl acetate was 94.7 acetic anhydride and β-naphthol using ceasium chloride under the optimum conditions as follows.n(acetic anhydride) : n(β-naphthol)= 1.3 : 1, ceasium chloride dosage 0.5 g, reaction time 40 min, reaction temperature 80 °C. The catalyst could remain relatively high activity when reused for 5 times.
