클로로술폰산 C화학적 특성, 용도, 생산

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.

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.

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.

반응 프로필

Chlorosulfonic acid is a strong oxidizing acid. Reacts violently with water, strong mineral acids and bases, alcohols, finely dispersed organic matter. Dangerously incompatible with combustible materials, nitrates, chlorates, metallic powders, carbides, picrates, and fulminates. Undergoes possibly violent reactions with acetic acid, acetic anhydride, acetonitrile, acrolein, acrylic acid, acrylonitrile, alkali, allyl alcohol, allyl chloride, ammonium hydroxide, aniline, butyraldehyde, cresol, cumene, diethyleneglycol methyl ether, diisopropyl ether, diphenyl ether, ethyl acetate, ethyl acrylate, ethylene chlorohydrin, ethylenediamine, ethylene glycol, glyoxal, hydrocarbons (hexane, heptane), hydrogen peroxide, isoprene, powdered metals, methyl ethyl ketone, propylene oxide, vinyl acetate. When heated to decomposition, Chlorosulfonic acid emits toxic fumes of hydrogen chloride and oxides of sulfur [Sax, 9th ed., 1996, p. 831]. Reaction with phosphorus accelerates out of control and culminates in an explosion [Heumann, K. et al., Ber., 1882, 15, p. 417]. Mixing chlorosulfuric acid and 98% sulfuric acid may evolve HCl [Subref: Anon, Loss Prev. Bull. 1977, (013), 2-3].

위험도

Toxic by inhalation; strong irritant to eyes and skin; causes severe burns. Can ignite combustible materials. Evolves hydrogen on contact with most metals.

건강위험

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.

Safety Profile

A poison irritant. See also SULFURIC ACID. Chlorosulfonic acid is corrosive, can cause severe acid burns and is very irritating to the eyes, lungs, and mucous membranes. It can cause acute toxic effects either in the liquid or vapor state. Inhalation of concentrated vapor may cause loss of consciousness with serious damage to lung tissue. Contact of liquid with the eyes can cause severe burns if the liquid is not immediately and completely removed. It also causes severe sh burns due to its highly corrosive action. Upon ingestion it

잠재적 노출

Used to make pesticides, detergents, pharmaceuticals, dyes, resins, sulfonated oils; intermediate for dyes and pharmaceuticals; and pesticides. Although no military designation has been assigned chlorosulfonic acid may have been used as a choking/pulmonary agent

운송 방법

UN1754 Chlorosulfonic acid (with or without sulfur trioxide), Hazard class: 8; Labels: 8-Corrosive material, 6.1-Poison Inhalation Hazard, Inhalation Hazard Zone B.

Purification Methods

Distil the acid in an all-glass apparatus, taking the fraction boiling at 156-158o. It reacts EXPLOSIVELY with water [Cremlyn Chlorosulfonic acid: A Versatile Reagent, Royal Society of Chemistry UK, 2002, p 308, ISBN 0854044981, Fehér in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 385 1963].

비 호환성

Explosively reacts with water, forming sulfuric and hydrochloric acid and dense fumes. Dangerously reactive, avoid contact with all other material. Violent reaction with many compounds, including reducing agents; alcohols, chemically active metals; combustible materials, strong acids, alkaline earth sulfides, aluminum carbides, aluminum, amines, calcium sulfide, carbides, chlorine trifluoride, glycerin, hydrides, hydrochloric acid, hydrogen peroxide, hydrogen sulfide, hydroxylamine, magnesium, metal powders, metal sulfides, molybdenum, phenylhydrazine, phosphorous red/friction, phosphorous trichloride, silicon, sulfides, sulfur, sulfur dioxide, sulfur/ friction, sulfuric acid, tungsten, hydrogen trisulfide, diphenyl ether, finely divided metals, silver nitrate. Contact with phosphorous may cause fire and explosions. Forms explosive material with ethyl alcohol. Attacks many metals; reaction with steel drums forms explosive hydrogen gas, which must be periodically relieved.
