Synthesis
Dichloroisocyanuric acid is manufactured by chlorination of cyanuric acid:[1]
- (C(O)NH)3 + 2 Cl2 → (C(O)NCl)2(C(O)NH) + 2 HCl
It is a colourless solid.
Mechanism of action
Dichloroisocyanuric acid is an oxidizer, reacting with water to form hypochlorous acid.
Although the bleaching agent in most chlorine based bleach is sodium hypochlorite, the sodium salt of dichloroisocyanuric acid, sodium dichloroisocyanurate, is the active ingredient in several bleach products. It is the active ingredient in many commercial disinfectant bacteriocides, algicides, and cleaning agents., for example the pulverized cleanser Comet.
