Nitric acid, sulphonitric acids

CPC v2.1 Code: 34233

About nitric acid, sulphonitric acids

cpc code 34233 covers the production of nitric acid and sulphonitric acids, which are essential chemicals used in a wide range of industries. These acids play a crucial role in the manufacturing of fertilizers, explosives, dyes, and various other chemical products. They are integral to the global economy, supporting the growth and development of numerous sectors, from agriculture to industrial production.

Production process

The primary production technique for nitric acid and sulphonitric acids involves the oxidation of ammonia. This process, known as the Ostwald process, involves the catalytic oxidation of ammonia to nitric oxide, which is then further oxidized to nitrogen dioxide. The nitrogen dioxide is then absorbed in water, resulting in the production of nitric acid. Sulphonitric acids are produced by combining nitric acid with sulfuric acid.

Production inputs

The main inputs required for the production of nitric acid and sulphonitric acids include ammonia, air, water, and sulfuric acid. Specialized equipment, such as catalytic converters, absorption towers, and distillation units, are also essential for the manufacturing process. Additionally, the industry relies on a skilled workforce with expertise in chemical engineering and process control.

Production outputs

The primary outputs of cpc code 34233 are nitric acid and sulphonitric acids. These chemicals are widely used in the production of 31210 Nitrogenous fertilizers, 20110 Basic chemicals, and 20120 Fertilizers and nitrogen compounds. They are also consumed by industries producing 20200 Pesticides and other agrochemical products and 20300 Paints, varnishes and similar coatings, printing ink and mastics.
