硫酸氢钠催化合成乙酸丙酯的研究

Synthesis of Propylaectate Catalyzed by Sodium Bisulfate

以硫酸氢钠为催化剂,实现了乙酸和丙醇的酯化反应,并对影响酯化率的各种因素进行了研究。结果表明：最佳反应条件为乙酸用量0.1 mol时,醇酸物质的量比为1.4,催化剂用量为0.10 g,15 mL环己烷作带水剂,在温度为78~85℃,反应时间1.5 h,酯化率达98%以上。

NaHSO4 was used as catalyst for estrification of Aetic acid with propanol and discussed the variant conditions in reaction of estrification.The result shows that the best reaction condition was： Based on 0.1mol acetic acid,molar ratio of propanol to acetic acid was 1.4,mass of catalyst was 0.10 g,the taking water reagent was 15 mL,reaction temperature was between 78~85 ℃,reaction time was 1.5 h.The yield of propyl acetate reached 98 %.
