研究了五种强酸性阳离子交换树脂对合成有机酯反应的影响。实验结果表明:D72型阳离子树脂的催化活性最好,其树脂用量为1.5g,冰醋酸与无水乙醇物质的量之比为1∶1.4,反应温度为70℃,反应时间为60min时为最佳条件。
The effects of five strongly acidic cation exchange resins on the reaction of synthetic organic esters were studied. The experimental results show that D72 cationic resin has the best catalytic activity, the resin dosage is 1.5g, the ratio of glacial acetic acid to absolute ethanol is 1: 1.4, the reaction temperature is 70 ℃ and the reaction time is 60min Good condition.
