摘　　要：以SnO为催化剂,苯甲酸与正丁醇反应合成了苯甲酸正丁酯。探讨了氧化亚锡催化酯化反应机理以及反应条件对产率的影响。结果表明:SnO具有一定的催化活性,在醇酸物质的量比为2:1、催化剂用量为反应物料总质量的1.75％、反应时间2.5 h、反应温度120～130℃的条件下,苯甲酸正丁酯的产率可达63％。The synthesis of n - butyl benzoate from benzoic acid and n - butanol was catalyzed by SnO. The catalytic esterification mechanism of SnO and the influence of reaction conditions on the yield of n - butyl benzoate were discussed. The results showed that SnO was an excellent catalyst for synthesizing n - butyl benzoate. The yield of n - butyl benzoate could reach over 63 % under the condition of molar ratio of n - butanol and benzoic acid 2: 1, amount of SnO catalyst 1.75 % (based on total amount of reaction mass) , reaction time 2 .5 h, reaction temperature 120 - 130 ℃.
