In the article, the kinetic laws, kinetics, and mechanism of the oxidative acetylation reaction of ethylene in the vapor phase were studied in detail in the 0.4%Rd+4%Cu+7%CH3 COOK/YuKTs catalyst. As a result of the research, the following optimal conditions for the reaction were selected: in the middle zone of the reactor at a temperature of 165°C, a volume velocity of 2000 h-1, a pressure of 4 atm, a ratio of ethylene to acetic acid of 4:1 and an oxygen content of 7% by volume. Under these optimal conditions, the activation energies of the reactions of vinyl acetate formation and ethylene oxidation are respectively equal to: Ea(VA) = 8.17 kcal/(mol∙K) and Ea(SO2) = 19.61 kcal/(mol∙ K). It was found that the rate of oxidation of ethylene is higher than the rate of formation of vinyl acetate when the temperature exceeds 220°C. The reaction mechanism of vinylacetate formation from ethylene and acetic acid in the presence of a palladium catalyst was proposed.
