Nitric Acid - The Chemical Company

Commercial grade nitric acid solutions are usually between 52% and 68% nitric acid. Production of nitric acid is via the Ostwald process, named after German chemist Wilhelm Ostwald. In this process, anhydrous ammonia is oxidized to nitric oxide, in the presence of platinum or rhodium gauge catalyst at high temperature of about 500K and a pressure of 9 bar.

Nitric Acid Treatment: DDPS - ddpsinc

Providing process solutions for recovery, cleaning, concentration. This results in a nitric acid/water mixture with a strength of up to almost 68 wt% nitric acid. The majority of nitric acid is used for the production of fertilizers. Other processes such as the production of explosives, pigments, rocket fuels or polyurethanes require higher concentrated nitric acid.

Nitric Acid - Imperial College London

Nitric Acid. It is made from ammonia by the Ostwald Process (developed in 1902 by the German chemist Wilhelm Ostwald, who got the Nobel prize in 1909). This process reacts together O 2 and NH 3 at 850°C and 5 atmospheres pressure, with the help of Platinum and Rhodium catalysts, to make NO. This is then oxidised to NO 2,...

Nitric Acid Products and Chemical Information | Brenntag

When nitrogen dioxide (NO2) reacts with water (H2O), nitric acid (HNO3) forms. Other names for nitric acid include spirit of niter, eau forte, aqua fortis, hydrogen nitrate, and acidum nitricum. While it is found in acid rain, nitric acid suppliers create it using a method called the Ostwald process.

Nitric Acid - an overview | ScienceDirect Topics

Nitric acid is a chemical of great commercial importance because of its use in the manufacture of explosives like nitroglycerine, trinitrotoluene, gum cotton (nitrocellulose), picric acid, etc., in the manufacture of nitrates, which are used as fertilizers, and in the manufacture of dyes, drugs, and artificial silk fibers. It is a strongly fuming, colorless, and liquid miscible with water in all proportions.

Selection of stainless steels for handling nitric acid (HNO3)

Nitric acid is strongly oxidising and attacks most metals but due to its powerful oxidising nature, it promotes the resistance of stainless steel to corrosion. Generally stainless steels are resistant to corrosion in nitric acid over a wide range of concentration and temperature.

The Fundamentals of Nitric Acid Passivation, Pickling and ...

Jan 26, 2017 · Pickling is very similar to the basic passivation process in that a bath of acidic chemicals is used to strip the surface of the steel. However, where the basic passivation process uses mild nitric acid, pickling uses a more intensive chemical mixture, such as hydrofluoric acid. This stronger acid strips the surface layer of the steel, removing impurities, weld burns, and free iron molecules—leaving an even, .
