摘要
以乙酸和环己醇为原料,自制的新型固体超强酸S O42-/Sb2O3/SiO2作催化剂,催化合成乙酸环己酯。反应结果表明,最优化条件是:n(乙酸):n(环己醇)=1.0:1.2,催化剂用量为0.8g,反应温度为145℃~160℃,反应时间为4h,酯化率可达94.7%。产品用折光率和红外光谱进行表征。
Cyclohexyl acetate was synthesized from acetic acid and cyclohexanol catalyzed by the new SO4^2-/Sb2O3 /SiO2 catalys made by the researcher himself. The experiment results showed that the optimum reaction conditions were as follows: when the molar ratio of cyclohexanol to acetic acid was 1:1.2, the dosage of SO4^2-/Sb2O3 /SiO2 was 0.8g and temperature of reactionis was 145-160℃, reflux time was 4 hour. The esterification yield reached to 94.7%. The product was characterized by refractive index and IR.
