Nitric Acid an overview ScienceDirect Topics

The nitric acid concentration process consists of feeding strong sulfuric acid and 55%–65% (v/v) nitric acid into the top of a packed dehydrating column at approximately atmospheric pressure. The acid mixture flows downward and concentrated nitric acid leaves the top of the column as 99% (v/v) vapor that contains a small amount of nitrogen dioxide and oxygen that result from dissociation of nitric acid.

Nitric acid Wikipedia

Nitric acid, also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid. The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO3, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid

Nitric acid -Ostwald's method-Industrial preparation of

Nitric acid is a strong mineral acid. It is a mono-basic acid. It is a strong oxidizing agent and can oxidize metals and nonmetals easily. It is used in the manufacture of fertilizers, silk industry, explosive materials such as (T.N.T) etc.

The Manufacture of Nitric Acid Johnson Matthey

These fertilisers, generally with high nitrogen contents, provide the active nitrogen in the form of ammonium nitrate or as nitrophosphate formed by the action of nitric acid on phosphate rock. For these processes “weak” nitric acid (55 to 65 per cent HNO 3) is usually employed. Certain territories, such as Japan, are exceptions to this generalisation, since nitrate fertilisers for domestic agriculture may not be suitable there, and consumption of the acid

Ostwald Process for Producing Nitric Acid

Nitric acid is a colorless 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 involves two steps.

Understanding the 3 Different Nitric Acid Production

The manufacturing of nitric acid for use in fertilizers, plastics, dyes, textiles, and other industrial products, has evolved to three industry-standard processes. They all produce acid with 60-68% concentration, and each uses essentially the same nitric acid plant design.

What Is the Ostwald Process?

2/20/2021· In this process, nitric acid is synthesized by the oxidation of ammonia. Prior to the introduction of the Ostwald process, all nitric acid was produced by distilling saltpeter — sodium nitrate (NaNO 3) or potassium nitrate (KNO 3) — with concentrated sulfuric acid. The Ostwald process now accounts for all industrial production of nitric acid, a chemical crucial to the fertilizer and explosives
