Characteristics

PSA:

62.75000

XLogP3:

1.10880

Appearance:

Chlorosulfonic acid appears as 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.

Density:

1.753 g/cm³ @ Temp: 20 °C

Melting Point:

-80 °C

Boiling Point:

60-64 °C @ Press: 2-4 Torr

Flash Point:

158ºC

Refractive Index:

1.4331

Water Solubility:

Solubility in water: reaction

Storage Conditions:

Store in a cool, dry, well-ventillated location. Separate from water, acids, alkalies, alcohols.

Vapor Pressure:

1 mm Hg ( 25 °C)

Vapor Density:

4 (vs air)

Explosive limit:

Permonosulfonic acid was being prepared by reacting chlorosulfonic acid & 90% hydrogen peroxide. A sample was stored overnight at 0 deg C, then removed to test tube rack. In 10 minutes it exploded.

Odor:

PUNGENT

Experimental Properties:

DECOMPOSED BY ALCOHOL & ACIDS.

Air and Water Reactions:

Fumes in air. Reacts exothermically and violently with water producing sulfuric acid, hydrochloric acid, and large quantities of dense white acid fumes [Merck, 11th ed., 1989]. Contact with water and metal produces explosive hydrogen gas (USCG, 1999). Chlorosulfonic acid reacts vigorously with water to generate gaseous HCl. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Chloride gas will be created in 0.04 minutes. Experimental details are in the following: "Development of the Table of Initial Isolation and Protective Distances for the 2008 Emergency Response Guidebook", ANL/DIS-09-2, D.F. Brown, H.M. Hartmann, W.A. Freeman, and W.D. Haney, Argonne National Laboratory, Argonne, Illinois, June 2009.

Reactive Group:

Acids, Strong Oxidizing

Reactivity Alerts:

Strong Oxidizing Agent

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, it 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].

Autoignition Temperature:

Corrosivity:

CORROSIVE MATERIAL.

Heat of Vaporization:

198 btu/lb= 110 cal/g= 4.6X10+5 J/kg (est)
