摘要
阐述了以SO42--TiO2/Al2O3固体超强酸为催化剂,以乙酸和环己醇为原料合成乙酸环己酯,探讨了影响酯化反应的各种因素,得出了酯化反应的最佳合成条件:催化剂的焙烧温度为500℃,n(乙酸)∶n(环己醇)为2.0∶1,催化剂质量为2.0 g,带水剂环己烷15 mL,反应时间2 h。在最佳合成条件下,酯收率达到94.1%。
Cyclohexyl acetate was synthesized from acetic acid and cyclohexyl alcohol in the presence of solid superacid catalyst SO4^2 --TiO2 /Al2O3. Factions of esterification reaction were stuelieel The optimal conditions of operation are as follows; the calanced temperatures of catalyst 500℃, n(acetic acid) ; n(cyclohexyl alcohol) 2.0 : 1, the amounts of catalyst 2. 0 g, cyclohane 15 mL,the reaction time 2 h. Under the optimal conditions of operation, the yields of cyclohexyl acetate is upto 94.1%.
