Abstract
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.
