Due to the dissolved nitrogen dioxide, the density of red fuming nitric acid is lower at 1.490 g/cm 3. An inhibited fuming nitric acid, either white inhibited fuming nitric acid (IWFNA), or red inhibited fuming nitric acid (IRFNA), can be made by the addition of 0.6 to 0.7% hydrogen fluoride (HF).
Mixtures of ordinary nitric acid in sulfuric acid therefore contain substantial amounts of water and are unsuitable for processes such as those that occur in the manufacture of trinitrotoluene. The synthesis of RDX and certain other explosives does not require oleum. [10] Anhydrous nitric acid, referred to as white fuming nitric acid, can be ...
CH 3 OH + HNO 3 → CH 3 NO 3 + H 2 O. A newer method uses methyl iodide and silver nitrate: [4] CH 3 I + AgNO 3 → CH 3 NO 3 + AgI. Methyl nitrate can be produced on a laboratory or industrial scale either through the distillation of a mixture of methanol and nitric acid, or by the nitration of methanol by a mixture of sulfuric and nitric acids.
N 2 O 5 + H 2 O → 2 HNO 3. Solutions of dinitrogen pentoxide in nitric acid can be seen as nitric acid with more than 100% concentration. The phase diagram of the system H 2 O − N 2 O 5 shows the well-known negative azeotrope at 60% N 2 O 5 (that is, 70% HNO 3), a positive azeotrope at 85.7% N 2 O 5 (100% HNO 3), and another negative one at ...
Strontium nitrate is typically generated by the reaction of nitric acid on strontium carbonate. [2] 2 HNO 3 + SrCO 3 → Sr(NO 3) 2 + H 2 O + CO 2 The reaction of nitric acid and strontium carbonate to form strontium nitrate
The industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: [12] HNO 3 + NH 3 → NH 4 NO 3. The ammonia required for this process is obtained by the Haber process from nitrogen and hydrogen. Ammonia produced by the Haber process can be oxidized to nitric acid by the Ostwald process.
This reaction removes NO 2 which limits the amount of O 3 that can be produced from its photolysis (reaction 4). HNO 3, nitric acid, is a sticky compound that can easily be removed onto surfaces (dry deposition) or dissolved in water and be rained out (wet deposition). Both ways are common in the atmosphere and can efficiently remove radicals ...
Another method involves the reaction of urea, nitric acid and sulfuric acid: [54] 2 (NH 2) 2 CO + 2 HNO 3 + H 2 SO 4 → 2 N 2 O + 2 CO 2 + (NH 4) 2 SO 4 + 2 H 2 O. Direct oxidation of ammonia with a manganese dioxide-bismuth oxide catalyst has been reported: [55] cf. Ostwald process. 2 NH 3 + 2 O 2 → N 2 O + 3 H 2 O
