p-Nitrotoluene 2-methyl-1;  4 hydroquinone;  reaction mechanism;  Kinetic models

Based on the successful development of the catalytic synthesis process of 2-methyl-1,4 hydroquinone, the reaction kinetics of the synthesis of 2-methyl-1,4 hydroquinone under the action of catalyst were studied, a series reaction mechanism was proposed, the reaction speed of the system was expressed by the change rate of the concentration of the system with time, the kinetic model was established, the parameters in the model were determined, and the proposed kinetic model was experimentally verified. Experiments show that in the temperature range of 356.15~368.15 K, the apparent activation energy of the reaction Eα=67.7750 kJ·mol-1, which is between 40~400 kJ·mol-1 of the general chemical reaction, belongs to the chemical reaction control process.
