首次在超声辅助硫酸氢钠的催化下,用乙酸酐和2-萘酚合成了乙酸2-萘酯,测定了产物的熔点,通过红外吸收光谱法对产物的结构进行了表征。最佳工艺条件:反应20min、催化剂硫酸氢钠用量为0.4g、反应温度为40℃,反应温度大幅降低,收率可达90.9%。 For the first time, 2-naphthyl acetate was synthesized from acetic anhydride and 2-naphthol catalyzed by ultrasonic-assisted sodium bisulfate. The melting point of the product was determined. The structure of the product was characterized by infrared absorption spectroscopy. The optimum conditions were as follows: the reaction time was 20min, the amount of catalyst sodium bisulfate was 0.4g, the reaction temperature was 40 ℃, the reaction temperature was greatly reduced, the yield was up to 90.9%.
