Nitric acid - Essential Chemical Industry

Some 99% acid is required for the manufacture of, for example, organic nitro-compounds for the explosives and dye industries. Nitric acid and water form an azeotropic mixture, with a maximum boiling point of 395 K, containing ca 68% nitric acid by mass; thus the concentrated acid cannot be obtained by distillation of the aqueous solution.

Industrial manufacturing of Nitric acid

Jan 25, 2016  The rate of oxidation of NO to NO2 can be increased 100 times using coke as catalyst. However this catalyst demands that oxidation should be carried out in non-aqueous medium since production of Nitric Acid involves absorption of NO2 into water hence the reaction is carried out in the absence of any catalyst.

Nitric acid - Wikipedia

Nitric acid (H NO 3), also known as aqua fortis (Latin for "strong water") 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%w/w (or, 68g of HNO 3 dissolved in 100ml of water).
