%X The oxidation of solid biurea with chlorine in aqueous solution to produce azodicarbonamide was experimentally studied in a 1 L agitated glass vessel with a four-blade paddle stirrer. Based on the film theory, a model is first developed for this system by taking the gas-liquid and solid-liquid mass transfer, solid dissolution, and instantaneous reaction between the dissolved reactants into consideration. The model can reasonably well represent the experimental data. According to the values of gas-liquid and solid-liquid mass transfer coefficients estimated with the proposed model, it is found that the gas-liquid mass transfer is a rate-controlling step in most cases, but the solid-liquid mass transfer becomes a rate-controlling step when the reaction is close to the end of this process.
