the mixture of nitric acid and sulfuric acid in the ratio of 1:2.
A continuous process to nitrate a nitratable aromatic compound utilizing nitric acid and sulfuric acid feed stocks is described.
Nitric Acid
in picric acid we cannot used direct nitration because of the phenol is very sensitive in oxidation of nitrate, to overcome this problem, we used a sulfuric acid added to phenol before the nitric acid. the reaction between NO2 and SO2 are reversible so the sulphate exchange with nitrate becoming tri nitrophenol
Nitric acid = Aqua Fortis, Spirit of Nitre Sulfuric acid = Oil of Vitriol, or simply Vitriol
the mixture of nitric acid and sulfuric acid in the ratio of 1:2.
4 methyl (3, 5 dinitro) phenylol
A continuous process to nitrate a nitratable aromatic compound utilizing nitric acid and sulfuric acid feed stocks is described.
Nitration: H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O Nitric Acid Nitrobenzene Nitration: H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O Nitric Acid Nitrobenzene Nitration: .................H2SO4 C6H6 + HONO2 ---------> C6H5NO2 + H2O .....Nitric Acid ......Nitrobenzene
Nitric Acid
Sulfuric acid, Hydrochloric acid, Nitric acid, Phosphoric Acid

Sulfuric acid is more stronger than Nitric acid, but Nitric acid is more reactive than Sulfuric acid.
Gold does not react with sulfuric acid.The only acid that gold reacts with is aqua regia: a mixture of nitric acid and hydrochloric acid, optimally in a molar ratio of 1:3.
Aqua Regia (mixture of concentrated sulfuric and nitric acids) is about your only hope. But please don't try this if you don't have a fume hood.
nitric acid be used insted of hypophrosphous acid
