【摘要】 以乙酸、正己醇为原料,直接酯化合成乙酸己酯,分别研究了反应温度、反应时间、原料配比、带水剂、催化剂用量等条件对合成反应的影响,确定了最佳工艺条件。该方法合成乙酸己酯的最佳工艺条件是:反应温度115℃;反应时间70min;n(正己醇)/n(乙酸)=1.2;催化剂用量为1g;带水剂苯用量为15mL(乙酸为0.3mol的情况下)。乙酸己酯的收率达到96.36%。更多还原

【Abstract】 The hexyl acetate was synthesized from n-hexanol and acetic acid by direct esterification.The effect of reaction temperature,reaction time,materials ratio,taling water reagent,the content of catalyst on the synthesis were studied,and the proper technological conditions were given as follows:the reaction temperature is 115 ℃,reaction time is 70 min,n(n-hexanol)/n(acetic acid)=1.2,the content of catalyst is 1 g,the taling water reagent(benzene) is 15 mL(when acetic acid is 0.3 mol). The yield of the product is 96.36%.更多还原
