Chemical compound

Dichloramine is a reactive inorganic compound with the chemical formula NHCl₂. 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.^[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

Reactions

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