CATALYST FOR PRODUCTION OF NITROUS PROTOXIDE AND METHOD OF NITROUS PROTOXIDE PRODUCTION Russian patent published in 2003 - IPC

FIELD: chemical, semiconductor, perfumery, medical and a food-processing industries. SUBSTANCE: invention is dealt with catalysts and methods of production of nitrous protoxide (N₂O)M using oxidation of ammonia by oxygen or oxygen-containing gas. Nitrous protoxide finds broad application in different areas of a national economy: in semiconductor, perfumery, medical and food-processing industry. The catalyst and a method of production of nitrous protoxide by oxidation of ammonia by oxygen or oxygen-containing gas at the presence of manganous active component, an iron oxide and oxide or blend of oxides of alkaline-earth metals are described. The catalyst contains as an active component composition representing blended amorphous oxidic phase of non- stoichiometric composition MnR_xO_y(0,05≤x≤2,24;2,08≤y≤5,36), where R - bismuth and / or lanthanide or blend of an amorphous oxidic phase of composition MnR_xO_y and crystalline manganous phase. Process of production of nitrous protoxide using oxidation of ammonia by oxygen or oxygen-containing gas at the presence of the manganous catalyst of indicated above composition is carried out under the temperature of 250-450 C. EFFECT: production of active and selective in respect of nitrous protoxide catalyst with the decreased share of active component. 6 cl, 1 tbl, 10 ex
