METHOD TO PREPARE CATALYST FOR CHEMICAL PROCESSES OF HYDROGENATION OF KETONES, NITRO COMPOSITIONS AND AMINATION OF ALCOHOLS Russian patent published in 1995 - IPC

FIELD: catalysts production. SUBSTANCE: method to prepare catalysts for chemical processes of hydrogenation of ketones, nitro compositions and amination of alcohols provides, that ammonium chromates of metals are produced by chromic acid mixing with copper, nickel or zinc or their mixture carbonates or oxides Produced compound is mixed with ammonium water. Chromates thermal decomposition is exercised. Catalyst is formed and reduced by hydrogen. In the process ammonium chromates of metals are mixed with oxides or hydrooxides, or carbonates, or chromates of copper and /or nickel, and /or cobalt, and /or metals of II-d group of chemical elements periodical system, and or aluminum. and /or manganese in presence of water or ammonium water. In the case, compositions of copper, nickel and cobalt are introduced in amount of 25 80 mol and composition of II-d group metals, aluminum and manganese are introduced in amount of 0,1 75,0 mol EFFECT: simplified technique. 3 cl, 1 tbl
