Halazone Usage And Synthesis

Chemical Properties

white powder

Originator

Clordiapenser,Molteni Farmaceutici SpA.

Uses

antiinfectant

Uses

Water disinfectant.

Manufacturing Process

20 kg p-aminosulfonyl benzoic acid was mixed with 400 L 0.5 N NaOCl. After an acidification with 100 L 1 N acetic acid, a precipitate dropped out. It was filtered off, washed and dried. The obtained 4-((dichloroamino)sulfonyl) benzoic acid had MP: 203°C.

Therapeutic Function

Antiseptic, Antiseptic

General Description

p-Dichlorosulfamoylbenzoic acid is a white, crystalline,photosensitive compound with a faint chlorine odor.Halazone is only slightly soluble in water at pH 7 but becomesvery soluble in alkaline solutions. The sodium salt ofhalazone is used to disinfect drinking water.

General Description

Fine white powder with an odor of chlorine.

Air & Water Reactions

Insoluble in water.

Fire Hazard

Flash point data for Halazone are not available, but Halazone is probably combustible.
