Inhalation Risk:A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C.
Effects of Short Term Exposure:The substance is very corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema. The effects may be delayed. Medical observation is indicated.
Effects of Long Term Exposure:Repeated or prolonged inhalation may cause effects on the lungs. The substance may have effects on the teeth. This may result in erosion.
Uses Chlorosulfuric Acid is used in the preparation of benzothiazepinylphosphonate bile acid transporter inhibitor. Also used in the preparation ofsulfated guar gum for potential use as an antioxidant. manufacture of sulfone Compounds, saccharin. As chlorosulfonating and condensing agent in organic syntheses. Chlorosulfonic acid is used as detergent and as an anti-contrail agent. It is used as an intermediate in the production of other substances such as pharmaceuticals and chemicals. It finds application in producing smoke screens.
