摘　　要：二溴次氮基丙酰胺(DBNPA)是一种理想的环保型杀菌灭藻剂和水处理剂。通过实验,探索了最佳合成方法,即在H_2O_2的作用下,使Br_2与氰基乙酰胺(CAA)溶液一起加热回流,可制备高产率的二溴次氮基丙酰胺,H_2O_2的作用是使反应中产生的HBr氧化为Br_2而被循环利用。2,2-Dibromo-3-nitrilopionamide (DBNPA)[10222-01-2] is a ideal environmental protection agent as biocide-algaecide and water treatment agent. The optimal synthetic method was found in the experiment. DBNPA was prepared efficiently by reacting CAA with Br_2 in the presence of H_2O_2. The action of H_2O_2 is that excessive HBr produced in the reaction was transformed into Br_2 which could be recycled.
