以冰乙酸和正丁醇为原料,纳米ZnO为催化剂催化合成乙酸正丁酯,探讨催化剂用量、酸醇物质的量比、反应时间等对反应结果的影响,对合成的产物进行红外光谱分析。结果表明,当酸醇物质的量比为1∶2.0,催化剂用量为0.8g(冰乙酸用量为0.1mol),反应温度为91～116℃,反应回流时间为3.0h,其酯化率可达86.72%。 Using glacial acetic acid and n-butanol as raw materials, the synthesis of n-butyl acetate catalyzed by nano-ZnO was investigated. The effects of catalyst dosage, molar ratio of acid to alcohol and reaction time on the reaction results were discussed. The synthesized products were analyzed by infrared spectroscopy. The results showed that when the molar ratio of alcohol to alcohol was 1: 2.0, the amount of catalyst was 0.8g (the amount of glacial acetic acid was 0.1mol), the reaction temperature was 91-116 ℃ and the reflux time was 3.0h, 86.72%.
