Synthesis of N,N′-Methylenebisacrylamide

Fan Zhenzhong Liu Yanmin Liu Qingwang (Petroleum Engineering Department of Daqing Petroleum Institute, Daqi ng 163318)  
N,N′-methylenebisacrylamide was synthesized f ro m acrylamide and urotropin. The optimum conditions were determined as follows: t he amount of acrylamide was 7.1 g, urotropin was 4.0 g, hydrochloric acid was 0. 2 mL,the reaction temperature was 78 ℃, and the reaction time was 150 min. The yield reached 84.5%. The test of the water absorption capacity showsed that the water absorption performance of water absorbing resin was excellent.
