The Researches on Synthesis of N-Dodecylacrylamide

以十二伯胺和丙烯酸为原料在室温条件下合成N-十二烷基丙烯酰胺,其结构经IR、1H NMR鉴定表征.通过单因素实验研究了溶剂种类、反应温度、反应时间及物料配比对产物产率的影响,从而建立正交实验得出合成N-十六烷基丙烯酰胺的最优工艺条件:以氯仿为溶剂,反应温度25℃,反应时间4h,物料配比为1∶1.1时,平均产率达到80；.
N-dodecylacrylamide was synthesised under moderate reaction condition by dodecanamine and acrylic,which was characterized by IR and H NMR.A variety of reaction effects were investigated such as solvent type,temperature,time and feed ratio which impact on the yield.Thus the optimum reaction condition of preparation of N-dodecylacrylamide obtained by orthogonal test were as follows:using trichloromethane as solvent,reaction temperature 25 ℃,reaction time 4 h,feed ratio 1.1,the average yield reached 80%
