用强酸性大孔树脂CAT601作催化剂,肉桂酸和乙醇作原料合成了肉桂酸乙酯并进行了表征。最佳合成工艺为:酸醇比为1∶7,催化剂用量为30%,反应时间6 h,转化率达90%以上;对大孔树脂的重复使用性能进行了测试,结果表明:大孔树脂重复使用8次后,催化活性保持不变。 The strong acid macroporous resin CAT601 was used as the catalyst, cinnamic acid and ethanol were used as raw materials to synthesize ethyl cinnamate and characterized. The optimum synthesis conditions were as follows: the ratio of acid to alcohol was 1:7, the amount of catalyst was 30%, the reaction time was 6 h, and the conversion rate was over 90%. The reusability of macroporous resin was tested. The results showed that the macroporous resin After 8 repetitions, the catalytic activity remains unchanged.
