설명

일반 설명

Nitric acid is generally used as a primary reagent for the nitration and oxidation of organic molecules. It is also used as a strong oxidizing agent in organic synthesis to perform oxidative transformations. In addition, nitric acid is also used in the manufacturing of intermediate for polyurethanes and polyamides production.

애플리케이션

Nitric acid is used:

• As an oxidizing agent with sulfuric acid to graft the carboxylic acid over CNT (carbon nanotubes) to produce CNT-COOH.
• In the combustion method to adjust the pH of the solution to 7. It is one of the steps in the preparation of mixed magnetite–hematite nanoparticles.
• As a nitrating agent with sulfuric acid in the synthesis of 8-nitro-7-hydroxy-4-methyl coumarin and 6-nitro-7-hydroxy-4-methyl coumarin from 7-hydroxy-4-methyl coumarin.
