METHOD OF PREPARING ANTIMONY-CONTAINING CATALYST FOR OXIDATIVE AMINATION OF ALKANES AND ALKENES Russian patent published in 2003 - IPC

FIELD: organic synthesis catalysts. SUBSTANCE: invention, in particular, relates to oxidative amination of propane or propylene into acrylonitrile. Catalyst having general formula V_aSb_bM_mN_nO_x, is prepared by heating aqueous mixture containing V₂O₅ and Sb₂O₃ at temperature between higher than about 100 C and 250 C, preferably 110-175 C and, most preferably, 120-160 C at autogenous pressure and stirring to form catalyst precursor. The latter is calcined to give final catalyst. Catalyst may be used for oxidative amination of other C2-C5-hydrocarbons into alpha- beta-unsaturated nitriles. EFFECT: increased catalytic activity and acrylonitrile-formation selectivity. 17 cl, 3 tbl, 25 ex
