Abstract

The article examines the steam phase activity of the synthesis of ethylene vinyl acetate catalyst consisting of palladium, copper and potassium acetates of high silicon zeolite (HSZ), expanded clay and bentonite separated from bentonite and γ-Аl2О3, the porosity of the structure, methods and techniques of preparation. Vinilacet synthesis is carried out in a pilot device using a catalyst containing 0,4%Рd+4%Cu+7%CH3COOK/HSZ a temperature of 165  ̊C (438,15 K), a pressure of 0.1 MPa(14,5 Psig), volumetric velocity of the vapor-gas mixture is 200 and the amount of oxygen in the mixture with ethylene is 7 volume/%. Also the duration is 2000 hours. During this time, the activity of the catalyst is 95-97% selectivity 370-350 grams of vinyl acetate / liter. catalysis. hours.
