- Abstract
Background. Vinyl chloride is one of the largest organic semi-products in the world in chemical production. Vinyl chloride production is the third after polyethylene and ethylene oxide. According to the forecast data of IHS, the current consumption of vinyl chloride in the period from 2010 to 2015 increased at a rate of 4.4% per year and by 4.2% over the next five years. Vinyl chloride is the main raw material for the production of PVC. Therefore, the study of the synthesis of vinyl chloride by the homogeneous catalytic method is a very urgent task. Purpose. Studying the process of obtaining vinyl chloride based on acetylene and hydrogen chloride using a homogeneous catalytic method. Methodology. Acetylene, hydrogen chloride, N-methylpyrrolidone, multicomponent catalysts containing hydrochloric acid, ammonium chloride, copper monochloride and powdered metal copper were used in the work. Originality. The synthesis of vinyl chloride was studied for the first time by a homogeneous catalytic method depending on the nature and amount of catalysts, the ratio of reactants. Findings. With increasing content of monovalent copper in the composition of the catalyst increases the yield of vinyl chloride. With an acetylene: hydrogen chloride ratio of 1: 1.11 and a reaction time of up to 5 hours, the maximum yield of vinyl chloride is up to 87.4%. The kinetic parameters of the synthesis of vinyl chloride are determined, with an increase in temperature from 40°C to 70°C, the yield and the average rate of formation of vinyl chloride increase. The effect of the ratio and feed rate of reactants on acetylene conversion was also investigated. It is established that with an increase in the feed rate of the reacting substances HCl: C2H2 = 1.1 from 19.8 l / g (HCl) and 18 l / g (C2H2) to 58.5 l / g (HCl) and 53.2 l / g (C2H2) increases acetylene conversion from 57.5% to 66.0%, respectively. This is due to the increase in the number of reacting particles in the synthesis process. [ABSTRACT FROM AUTHOR]
