Dichloramine is a reactive inorganic compound. It has the formula N H Cl₂. The yellow gas is unstable and reacts with many materials.[1] 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.

Synthesis

Dichloramine can be prepared by a reaction between monochloramine and chlorine or sodium hypochlorite:[1]

NH₂Cl + Cl₂ → NHCl₂ + HCl

Reaction

Dichloramine reacts with hydroxyl ion, which can be present in water or comes from water molecules, to yield nitroxyl radical and the chloride ion.[2]
