Synthesis of n-Amyl Acetate Using Titanic Sulfate as Catalyst

以硫酸钛为催化剂,通过乙酸和正戊醇反应合成了乙酸正戊酯,并探讨了诸因素对产率的影响。实验表明,硫酸钛具有良好的催化活性,并得到最佳反应条件:醇酸摩尔比1.3∶1,催化剂用量占反应物料总量的1.0%,反应时间60 min,反应温度为113℃左右,产率可达89.11%。

The synthesis of n-amyl acetate from acetic acid and n-pentanol using titanic sulfate as catalyst was studied.Some effects on product yield were discussed.It showed that titanic sulfate had good catalytic activity.Optimum reaction conditions were gained as follows： molar ratio of n-pentanol and acetic acid was 1.3：1,the amount of catalyst was 1.0%（based on the total reactants）,the reaction temperature was about 113 ℃,and the reaction time was 60 min.The yield can reach 89.11%.
