چکیده: 

Foaming agents, whether physical or chemical, are substances that reduce the density of polymer products, and they are extensively utilized in the polymer industry. This paper presents a novel method for synthesizing azodicarbonamide (ADCA), a foaming agent with broad applications across various chemical sectors, including polymer and plastic industries. The process begins with the synthesis of hydrazodicarbonamide (Biurea) through the reaction of urea and hydrazine. Subsequently, azodicarbonamide is produced via the electrochemical (anodic) oxidation of Biurea in the presence of potassium bromide as a catalyst. The resulting compounds were characterized using FTIR and UV-Vis spectroscopies. In the FTIR spectroscopy of ADCA, the -NH peak of Biurea at 3300 cm⁻¹ is no longer observed. Meanwhile, in the UV-Vis spectroscopy of ADCA, a peak is detected at λmax = 424 nm. These findings indicate the complete conversion of Biurea to ADCA.
