FIELD: chemistry.
SUBSTANCE: proposed catalyst contains a complex of catalytically active oxides, including oxides of rubidium, cerium, chrome, magnesium, iron, bismuth, molylbdenum and at least, one of nickel or nickel with cobalt. The ratio of components is presented by the following general formula: RbaCebCrcMgdAeFefBigMo12Ox, where A is Ni or a combination of Ni and Co, a approximately ranges from 0.01 to 1, b approximately ranges from 0.01 to 3, c approximately ranges from 0.01 to 2, d approximately ranges from 0.01 to 7, e approximately ranges from 0.01 to 10, f approximately ranges from 0.01 to 4, g approximately ranges from 0.01 to 4, and x is a number, defined by valency of other present elements. "b"+"c" is greater than g. The catalyst does not contain manganese, noble metal or vanadium. The carrier is chosen from a group comprising silica gel, aluminium oxide, zirconium oxide, titanium oxide or their mixture. The catalyst is used for oxidative ammonolysis of olefin, chosen from a group containing isobutylene or their mixture, with formation of acrylonitrile, metacrylontrile and their mixture, respectively.
EFFECT: high activity of the catalyst.
