SUPPORTED CATALYST, METHOD OF PREPARING CATALYST AND METHOD OF PREPARING CARBOXYLIC ACID SALTS Russian patent published in 2000 - IPC

Abstract RU 2157727 C2

FIELD: oxidation catalysts. SUBSTANCE: invention provides supported catalyst for production of carboxylic acid salts distinguishing by consisting of (i) alkali-resistant carrier, (ii) a multitude of fixing metal particles (platinum, palladium, ruthenium, gold, or their mixtures) dispersed and partly imbedded into carrier, non-imbedded part of these particles having "non-imbedded surfaces", in which fixing metal is in elementary state, and (iii) coating of catalytically active metal (copper, cobalt, nickel, cadmium, or their mixture) in elementary form bound to and covering at least some of above-mentioned "non-imbedded surfaces" of fixing metal. Outer side of coating has catalytically active surface. EFFECT: increased catalytic activity. 23 cl, 2 dwg, 3 tbl, 15 ex
