The Ostwald process begins with burning ammonia.Ammonia burns in oxygen at temperature about 900 °C (1,650 °F) and pressure up to 8 standard atmospheres (810 kPa) [4] in the presence of a catalyst such as platinum gauze, alloyed with 10% rhodium to increase its strength and nitric oxide yield, platinum metal on fused silica wool, copper or nickel to form nitric oxide (nitrogen(II) oxide) and ...
Nitric acid is an inorganic compound with the formula H N O 3. It is a highly corrosive mineral acid. [6] ... Industrial nitric acid production uses the Ostwald process.
Ostwald invented a process for the inexpensive manufacture of nitric acid by oxidation of ammonia. He was awarded patents for this process. [ 14 ] Ostwald's patent made use of a catalyst and described conditions under which the yield of nitric acid was near the theoretical limit .
The Ostwald process is a chemical process for production of nitric acid (HNO 3), which was developed by Wilhelm Ostwald (patented 1902). It is a mainstay of the modern chemical industry and provides the raw material for the most common type of fertilizer production, globally (for example, ammonium nitrate , a common fertilizer, is made by ...
Nitric acid is generated via the Ostwald process by oxidation of ammonia with air over a platinum catalyst at 700–850 °C (1,292–1,562 °F), ≈9 atm. Nitric oxide and nitrogen dioxide are intermediate in this conversion: [44]
Ammonia is also used for the production of plastics, fibres, explosives, nitric acid (via the Ostwald process), and intermediates for dyes and pharmaceuticals. The industry contributes 1% to 2% of global CO 2. [2] Between 18–20 Mt of the gas is transported globally each year. [3]
Naturally, Gatorade’s exact nutritional value will depend on which formula you choose. For instance, Gatorade G2 (which is Gatorade’s lower-calorie cousin) contains only 40 calories in a 16 ...
