applications

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.
Also 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
