The present invention relates to a process for the preparation of N-substituted acrylamides of the general formula CH2═CH—CONHR, wherein, R is alkyl group having carbon 1 to 22 or acyl group having carbon 1 to 18. The process for the preparation of the N-substituted acrylamides comprises reacting acrylamide with alkyl acyl chloride in the presence of Lewis acid catalyst in an organic solvent at a temperature ranging between room temperature to 50° C. for a period ranging between 1 hour to 24 hours.
本发明涉及一种制备一般式为CH2═CH—CONHR的N-取代丙烯酰胺的方法,其中R为碳数为1到22的烷基或碳数为1到18的酰基。制备N-取代丙烯酰胺的方法包括在有机溶剂中,在室温至50℃的温度范围内,在路易斯酸催化剂存在下,将丙烯酰胺与烷酰氯反应1小时至24小时。
