【摘要】 确定了以甲醛、丙烯酰胺为原料,水为反应介质,脂肪胺为催化剂,合成 N-羟甲基丙烯酰胺的最佳条件为:甲醛与丙烯酰胺的摩尔比1.0—1.1,反应温度40℃,反应时间40—60分钟,pH 值控制在9.6左右,可得较好产率的高纯度产品。得出合成 N-羟甲基丙烯酰胺的反应速率方程为:r=k[CH²O][AM][CAT)^1→0,并计算出表观活化能为43.96干焦/摩尔。更多还原

【Abstract】 The synthesis of N-methylolacrylamide starting from formaldehyde and acry-lamide in the presence of an aliphatic amine as catalyst has been studied.The optimum conditions are as follows:mole ratio of formaldehyde/acrylamide,1.0—1.1;pH,9.5—10;reaction temperature,40—50℃;reaction time,40—60 minutes.Crystals with high purity and good yield are obtained.The reaction rate equation has been established as r=k〔CH₂O〕〔AM〕〔CAT〕^?.The apparent activation energy is 43.96kJ/mol.更多还原
