Dichloramine
Chemical compound
Dichloramine (IUPAC name: Azonous dichloride) is a reactive inorganic compound with the chemical formula N H Cl2. It is one of the three chloramines of ammonia, the others being monochloramine (NH2Cl) and nitrogen trichloride (NCl3). This yellow gas is unstable and reacts with many materials. It is formed by a reaction between ammonia and chlorine or sodium hypochlorite. It is a byproduct formed during the synthesis of monochloramine and nitrogen trichloride.
01Synthesis
Dichloramine can be prepared by a reaction between monochloramine and chlorine or sodium hypochlorite, which forms hydrogen chloride as a byproduct:
- NH2Cl + Cl2 → NHCl2 + HCl
It also occurs as a reaction between urea in urine and hypochlorite:
- 4 HClO + CO(NH2)2 → CO2 + 3 H2O + 2 NHCl2
02Reactions
Dichloramine reacts with the hydroxide ion, which can be present in water or comes from water molecules, to yield nitroxyl and the chloride ion.
