| | Halazone Usage And Synthesis |
| Chemical Properties | white powder | | Originator | Clordiapenser,Molteni Farmaceutici SpA. | | Uses | Water disinfectant. | | Uses | antiinfectant | | 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. |
