Ostwald Process NO Oxidation

4NH3 + 5O2 → 4NO + 6H2O

अवलोकन

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.

रोजमर्रा का उदाहरण

Nearly all explosives, from TNT to ammonium nitrate, begin with nitric acid produced by this catalytic oxidation of ammonia.

औद्योगिक महत्व

The Ostwald process produces virtually all the world's nitric acid, essential for fertilizers (ammonium nitrate), explosives, and chemical manufacturing.
