In the article, the kinetic laws and kinetics and mechanism of the oxidation acetylationreaction of ethylene in the vapour phase were studied in detail in a catalyst containing0,4%Рd+4%Cu+7%CH3COOK/HSZ. It was found that the total rate of the reaction was proportionalto the amount of unmodified and modified active sites of palladium (not clusters). Excess amountsof the modifier (both potassium acetate and copper) have been shown to block active sites byreducing catalyst efficiency.
