synthetische

Hypochlorous acid is obtained by dissolving chlorine in water, or by addingbleaching powder or sodium hypochlorite to water. A better method of pro-duction is passing chlorine gas into a well-agitated suspension of mercuricoxide:
2Cl2 + 2HgO + H2O → HgO•HgCl2 + 2HOCl
or by distilling chlorine hexahydrate and mercuric oxide at low pressure:
2Cl2•6H2O + HgO → 2HOCl + HgCl2 + 5H2O
The latter process can yield a 25% acid solution.
Hypochlorous acid also may be obtained by hydrolysis of chlorine monoflu-oride:
ClF + H2O → H+ + F¯ + HOCl
The above reaction may be explosive and is not recommended for preparinghypochlorous acid.

Definition

ChEBI: A chlorine oxoacid with formula HOCl; a weak, unstable acid, it is the active form of chlorine in water.

Hazard

Irritant to skin and eyes.
