Dichloroisocyanuric acid, also known as dichlor or dichloro-s-triazinetrione and is marketed under many names (e.g. troclosene), is a chemical compound with the formula (C(O)NCl)2(C(O)NH).
Dichloroisocyanuric acid is manufactured by chlorination of cyanuric acid:
- (C(O)NH)3 + 2 Cl2 → (C(O)NCl)2(C(O)NH) + 2 HCl
It is a colourless solid.
Mechanism of action
This section is missing information about why it is used over hypochlorite — something to do with cyanuric acid?. (January 2022)
Dichloroisocyanuric acid is an oxidizer, reacting with water to form chlorine gas.
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 commercial disinfectant bacteriocides, algicides, and cleaning agents such as the pulverized cleanser Comet.
