오스트발트법 NO 산화

4NH3 + 5O2 → 4NO + 6H2O

개요

Ammonia is catalytically oxidized to nitric oxide over a platinum-rhodium gauze catalyst at about 850 C in the Ostwald process. Nitrogen is oxidized from -3 in NH₃ to +2 in NO. The NO is further oxidized to NO₂ and absorbed in water to make nitric acid. This process links the Haber process to nitric acid production.
