화학적 성질
Chlorosulfonic acid, ClS03H, also known as chlorosulfuric acid and sulfuric chlorohydrin, is an colorless to light yellow oily liquid. It is formed from sulfur trioxide and hydrogen chloride, but decomposes in water to form hydrochloric acid and sulfuric acid.It is a vigorous dehydrating agent and is used in manufacturing synthetic drugs,poison gas, and saccharin.

| 화재 위험 | Special Hazards of Combustion Products: Decomposes into irritating and toxic gases· EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily.Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion on contact with many substances. |
| 화재 가능성 | Not combustible, but if involved in a fire decomposes rapidly to produce hydrogen chloride, sulfur dioxide, sulfuric acid. Evolves hydrogen on contact with moist metals. Closed containers may rupture violently. |
| 건강 유해성 | INHALATION: vapor extremely irritating to lungs and mucous membranes. Vapor has such a sharp and pentrating odor that inhalation of severely toxic quantities is unlikely unless it is impossible to escape the fumes. CONTACT WITH EYES OR SKIN: liquid acid will severely burn body tissue. (USCG, 1999) |
용도
용도
생체에 대하여 격하게 작용하고, 피부에 접하면 심한 약상을 일으키며 허용 농도는 명확하지 않다. 공중의 수분과 반응하여 염산과 황산으로 분해하므로 양자의 상승 작용이 있다고 생각해도 좋다. 습한 공기중에서는 발연한다. 물과 격렬하게 반응하여 황산과 염산을 생성한다. 장시간 가열하면 황산, 이산화황, 염소로 분해한다. 피부를 심하게 침식한다.
용도
염소화제, 술폰화제로 사용된다.합성 세제의 제조 등에 쓰인다.
용도
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.
일반 설명
A colorless to yellow colored fuming liquid with a pungent odor. Density 14.7 lb / gal. Causes severe burns. Very toxic by inhalation. Corrosive to metals.
