CATALYST BASED ON PALLADIUM, GOLD, ALKALINE METAL AND LANTHANIDE AND METHOD OF SYNTHESIS OF VINYL ACETATE Russian patent published in 2002 - IPC

Abstract RU 2193553 C2

FIELD: organic chemistry, chemical technology, catalysts. SUBSTANCE: invention relates to synthesis of vinyl acetate from acetic acid, ethylene and oxygen or oxygen-containing gases. Process is carried out in gaseous phase using heterogeneous catalyst comprising palladium and/or its compounds, gold and/or its compounds, alkaline metal compounds and at least one lanthanide metal and/or its compounds distributed on carrier. Lanthanide metal content is 0.01-1 wt.-% of total mass of catalyst. Preferably used lanthanide metals are praseodymium, samarium, europium, neodymium, dysprosium. EFFECT: enhanced effectiveness of catalyst, increased yield of vinyl acetate. 8 cl, 1 tbl, 7 ex
