CATALYST AND NITROUS OXIDE PREPARATION METHOD Russian patent published in 2003 - IPC

FIELD: oxidation catalysts and inorganic compounds technology. SUBSTANCE: catalyst contains manganese-containing active component, alkali metal oxide or oxide mixture, and alumina, said active component being, more specifically, mixed amorphous oxide phase with non-stoichiometric composition: MnBi_yO_y(0,05≤x≤2,24;2,08≤y≤5,36) or mixture of amorphous phase MnBi_xO_y and crystalline manganese- containing phase. Nitrous oxide is prepared in presence of indicated catalyst via oxidation of ammonia with oxygen or oxygen-containing gas at 250-450 C. Product is intended to be used in semiconductor engineering, perfumery, medicine, and food industry. EFFECT: enhanced activity and selectivity of catalyst at lower active component content. 6 cl, 1 tbl, 9 ex
