Nitric acid is a colourless liquid that is used in the manufacture of inorganic and organic nitrates and nitro compounds for fertilizers, dye intermediates, explosives, and many different organic chemicals. Nitric acid is most commonly manufactured by Ostwald process. The Ostwald process converts ammonia to nitric acid and
MANUFACTURE. Nitric acid is manufactured by three methods. 1. From Chile saltpetre or nitrate. 2. Arc process or Birkeland and eyde process. 3. Ostwald's process or Ammonia oxidation process. 1. From Chile saltpeter or nitrate. It is the first commercial process of manufacture of nitric acid from sodium nitrate extracted
10 Nov 2016 Nitric acid is most commonly manufactured by Ostwald process. The Ostwald process converts ammonia to nitric acid and involves two steps. In step 1, ammonia is oxidized to form nitric oxide and also nitrogen dioxide. Then in step 2, the nitrogen dioxide that was formed is absorbed in water.
The formation of nitrogen dioxide occurs for concentrated acid and nitric oxide for dilute acid. Nitric acid is made from ammonia in a three-step process known as the Ostwald process. In this reaction, ammonia undergoes catalytic oxidation to form nitrogen monoxide (nitric oxide (NO) and water.
It is used in the manufacture of fertilizers, silk industry, explosive materials such as (T.N.T) etc. INDUSTRIAL PREPARATION OF NITRIC ACID. OSTWALD' s METHOD. OSTWALD'S METHOD. Materials used: Ammonia gas. Water Oxygen gas. CATALYST. Platinum. DETAILS OF PROCESS. First step. PRIMARY OXIDATION
