NO + NO 2 + 2 NaOH → 2 NaNO 2 + H 2 O NO + NO 2 + Na 2 CO 3 → 2 NaNO 2 + CO 2. The product is purified by recrystallization. Alkali metal nitrites are thermally stable up to and beyond their melting point (441 °C for KNO 2). Ammonium nitrite can be made from dinitrogen trioxide, N 2 O 3, which is formally the anhydride of nitrous acid: 2 ...
2 NaNO 2 → Na 2 O + NO + NO 2. Sodium nitrite can also be used in the production of nitrous acid: 2 NaNO 2 + H 2 SO 4 → 2 HNO 2 + Na 2 SO 4. The nitrous acid then, under normal conditions, decomposes: 2 HNO 2 → NO 2 + NO + H 2 O. The resulting nitrogen dioxide hydrolyzes to a mixture of nitric and nitrous acids: 2 NO 2 + H 2 O → HNO 3 ...
A nitrate nitrite, or nitrite nitrate, is a coordination complex or other chemical compound that contains both nitrite (NO − 2) and nitrate (NO − 3) anions. They are mixed-anion compounds , and they are mixed-valence compounds .
Calcium nitrite is an inorganic compound with the chemical formula Ca(NO 2) 2. In this compound, as in all nitrites, nitrogen is in a +3 oxidation state. It has many applications such as antifreeze, rust inhibitor of steel and wash heavy oil. [1]
Ammonium nitrite is a chemical compound with the chemical formula [NH 4]NO 2. It is the ammonium salt of nitrous acid. It is composed of ammonium cations [NH 4] + and nitrite anions NO − 2. It is not used in pure isolated form since it is highly unstable and decomposes into water and nitrogen, even at room temperature.
An example of chelating nitrite is [Cu(bipy) 2 (O 2 N)]NO 3 – "bipy" is the bidentate ligand 2,2′-bipyridyl. This bonding mode is sometimes described as κ 2O,O-NO 2.. The kinetically-favored O-bonded isomer [(NH 3) 5 Co−ONO] 2+ converts to [(NH 3) 5 Co−NO 2] 2+. In its reaction with ferric porphyrin complexes, nitrite gives the O ...
Alkyl nitrites are also used in the formation of oximes with the stronger carbon acids and acid or base catalysis for example in the reaction of 2-butanone, ethyl nitrite and hydrochloric acid forming the oxime, [7] the similar reaction with phenacyl chloride, [8] or the reaction of phenylacetonitrile with methyl nitrite and sodium hydroxide. [9]
Nickel(II) nitrite is an inorganic compound with the chemical formula Ni(NO 2) 2. [1] Anhydrous nickel nitrite was first discovered in 1961 by Cyril Clifford Addison, who allowed gaseous nickel tetracarbonyl to react with dinitrogen tetroxide , yielding a green smoke.
