In the article, the thermodynamics of the oxychlorination processes of ethylene in the presence of oxygen under the influence of hydrogen chloride were studied and the mechanism of the oxychlorination reaction was proposed. Kinetic equations describing the rate of formation of 1,2-dichloroethane and carbon dioxide were proposed based on the study of the mechanism of the process. The laws of formation of complete oxidation products of oxychlorination of ethylene with hydrogen chloride in the presence of oxygen in the presence of catalysts obtained for the oxychlorination reaction of ethylene with hydrogen chloride in the presence of oxygen were studied in a fluidized bed reactor designed for the oxychlorination reaction of ethylene in the presence of oxygen under the influence of hydrogen chloride. The temperature range is 210-240 ℃, the linear velocity of gases is 5.5-7 cm/sec, and the contact time of the oxychlorination reaction of conditioned ethylene with hydrogen chloride in the presence of oxygen is 8.5-9.5 sec. The ethylene oxychlorination reactor consists of a 32.5 m column apparatus with a diameter of 3.5 m. The operating modes of the reactor designed for the oxychlorination of ethylene under the influence of hydrogen chloride in the presence of oxygen were determined, and the material and heat balance of the reactor designed to carry out the oxychlorination reaction was calculated. The purpose of the work is to study the thermodynamic and kinetic laws of the oxychlorination processes of ethylene under the influence of hydrogen chloride in the presence of oxygen and to create a technology for obtaining vinyl chloride.
