摘要
研究了以富马酸和甲醇为原料,强酸型离子交换树脂为催化剂合成富马酸二甲脂。探讨了反应时间、催化剂用量、原料比等工艺参数对DMF收率的影响。该法具有操作简便,反应条件温和,产品纯度高等优点。并对富马酸二甲酯的防霉保鲜效果进行了初步研究。
A ion exchange resins was studies for the esterification of fumaric acid with methanol in this paper.The influences of reaction time,raw material ratio and amount of catalyst used on the yield of DMF were investigated.The method had advantages of simple operation,mild reaction conditions and high purity of the product.The antiseptic action and keeping fresh of DMF were studied.
