Azodicarbonamide was obtained by electrochemical oxidation of biruea utilizing SnO2 Sb2O3/Ti electrode as anode that was prepared by thermal decomposition method. The amount of current density、power、NaBr、H2SO4 and temperature on azodicarbonamide yield and current efficiency were studied by orthogonal experiment and mono-factor tests. The optimum conditions are: current density 0.23 A?cm-2、power 0.128 F、NaBr 8 g?L-1、H2SO4 147g?L-1、temperature 40 ℃, the yield of azodicarbonamide reached 94%，current efficiency was 89%. The cyclic voltammetry curves of SnO2 Sb2O3/Ti anode shows that the speed of electrochemical synthesis azodicarbonamide was controlled by the procedure of Brad combined to bromine, the anodic process conform to the EC mechanism.
