The apparent rate of heterogeneous medium-rate reaction is jointly controlled by liquid-liquid mass transfer performance and intrinsic kinetics. Realizing the matching of them can significantly enhance the efficiency of the reaction. Here, the dehydrochlorination reaction of 1,1,2-trichloroethane with NaOH solution is used as an example to investigate the matching relation between intrinsic kinetics and mass transfer efficiency of medium-rate reactions. Firstly, an apparent reaction model considering mass transfer performance, intrinsic kinetics and physical properties of the system was established. The accuracy of the model was experimentally verified in a standard stirred tank. Based on the model, the mass transfer coefficient matching the intrinsic reaction kinetics at 51 ℃ should beyond 100 s−1, which requires to be achieved in mass transfer intensification reactors instead of conventional stirred tank. Therefore, a rotor-stator homogenizer and a rotating packed bed were used. The experimental results in these two reactors well demonstrated the model prediction.
