N-羟甲基丙烯酰胺上游产品

N-羟甲基丙烯酰胺下游产品

N-羟甲基丙烯酰胺制备

（1）丙烯酰胺与甲醛缩合法在弱碱性条件下，将丙烯酰胺与37%的甲醛水熔液反应而制得。也可由丙烯酰胺与甲醛在脂肪胺催化剂催化下反应制得N-羟甲基丙烯酰胺。工艺流程：向装有回流冷凝器和搅拌器和三口瓶中加入一定量丙烯酰胺和37%甲醛水溶液，置于恒温水浴中，待丙烯酰胺溶解、水浴升至所需温度时，加入一定量的脂肪胺催化剂，反应完后将反应液脱水，干燥、结晶，分离出晶体，干燥，然后测定含量和熔点合格即为产品。最佳工艺条件为甲醛：丙烯酰胺=1：（1.1-1.0）（mol比），反应温度40-50℃，反应时间40-60min，PH值控制在9.6左右。在此条件下，丙烯酰胺的转化率达92.5%。用水作溶剂即安全又经济。结晶后的母液可循环使用，降低生产成本。一次结晶可得到含量为98%-99%的产品，熔点76-78℃，与文献值78.5-79接近。（2）丙烯腈水解法以28%工业丙烯酰胺水溶液（丙烯腈水解液）与甲醛水溶液在苛性钠催化下，以亚硝酸钠为阻聚剂合成而得。工艺流程：将28%工业丙烯酰胺水溶液、37%甲醛水溶液和苛性钠加入装有搅拌器、回流冷凝管的三口瓶中，不搅拌，控制温度在45-50℃。保持45-50min。然后冷却，结晶，过滤得粗产品。用乙酸乙酯对粗产品进行重结晶（70℃下溶解）即得精制品，收率可达72%。本法与甲醇交换法相比，不使用溶剂二氯甲烷，不必进行溶剂回收，安全、无毒；与离子交换法相比，弱碱性离子交换树脂昂贵，用后需再生；与传统苛性钠催化法相比，不需用结晶丙烯酰胺，简化了合成工艺。（3）丙烯酰胺与多聚甲醛缩合由丙烯酰与多聚甲醛缩合制得N-羟甲基丙烯酰胺。以三氯乙烯为溶剂，金属钠二甲苯胶体为催化剂，丙烯酰胺与多聚甲醛在50℃反应1h，收率达93%。
