物理形态与操作说明

  • Exists only in solution; Light blue liquid; [Merck Index]
  • Solid
  • When heated to decomposition it emits highly toxic fumes of /nitroxides/.
  • In water, it changes quickly into nitric oxide and nitric acid. Forms stable, water-soluble nitrites with Li, Na, K, Ca, Sr, Ba, Ag. Does not form salts with weak polyvalent cations like Al or Be. Forms stable esters with alcohols.
  • Stable only in solution
  • Nitrous acid decomposes into nitric oxide and nitric acid. It can also react as either an oxidizing or reducing agent.

数据库记载的用途

  • Formed as a product of combustion and when nitrogen dioxide reacts with water; Used to make diazotizing compounds and as a source of nitric oxide; [HSDB]
  • Formation of diazotizing compounds by reaction with primary aromatic amines, source of nitric oxide
  • Nitrous acid is used in chemical synthesis. (L1615)
  • Formed by the action of strong acids on inorganic nitrites.
  • Nitrous acid is not an article of commerce owing to its inherent instability. Sodium nitrite serves as the primary industrial source for nitrous acid in organic syntheses, for instance in the diatozation and nitrosation of aromatic amines. Under controlled conditions of acidification, the nitrous acid generated can react before excessive decomposition occurs.
  • ... also formed when nitrogen dioxide (NO2) reacts with water
