固体酸催化合成亚甲基双丙烯酰胺的实验研究

S ynthesis of Methylene diacrylamide with Solid acid Catalyst

在固体酸催化剂和阻聚剂存在下,反应温度55～60℃,水解的丙烯腈与甲醛溶液作用,合成N.N^1—亚甲基双丙烯酰胺,讨论了各种因素对产品收率和纯度的影响,该法产品的收率高达88%,大大缩短了反应周期,减少了副产物的生成.

This text has discussed the method that hydrolyted Ac rylonitrile compound with formaldehyde solution to synthesis N° N'-methylene diacrylamide in presence of a solid acid catalyst and inhibitor ,and the temperature of the reaction in 55-60℃. And had discussed all kinds of the factors that affect the yield and purity of the product,the yield of the product can reach to 88% if using this method ,and greatly decorates the reaction period ,reducing the production of the byproduct.
