7790-94-5 Usage

General Description

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.

Incompatibilities

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.

Shipping

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

Chemical Properties

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.

Hazard

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

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.

Uses

manufacture of sulfone Compounds, saccharin. As chlorosulfonating and condensing agent in organic syntheses.

Reactivity Profile

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].

Health Hazard

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.

Potential Exposure

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

Chemical Properties

Chlorosulfonic acid is a highly corrosive, colorless to yellow, slightly cloudy, fuming liquid with a sharp odor.

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].

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
