Chloroform Chemical Properties,Uses,Production


Chloroform is a trichlorinated organic substance with the chemical formula of CHCl3. It is a clear liquid at room temperature and has a pleasant, sweet odor. Chloroform is only slightly soluble in water and evaporates quickly into surrounding air, increasing the risk of inhalation exposure. In addition, chloroform persists for a long time in both water and air. There are no natural sources of chloroform, but this contaminant enters the environment through a variety of industrial operations, including the chlorination of water. Humans can be exposed to chloroform through inhalation, ingestion, and dermal contact.
Chloroform has a relatively narrow margin of safety and has been replaced by better inhalation anesthetics. In addition, it is believed to be toxic to the liver and kidneys and may cause liver cancer. Chloroform was once widely used as a solvent, but safety and environmental concerns have reduced this use as well. Nevertheless, chloroform has remained an important industrial chemical.

Chemical Properties

Colorless liquid


Chloroform (CHCl3) was first discovered in 1831 by American physician Samuel Guthrie; and independently a few months later by Frenchman Eugène Soubeiran and Justus von Liebig in Germany. Chloroform was named and chemically characterised in 1834 by Jean-Baptiste Dumas. Its anaesthetic properties were noted early in 1847 by Marie-Jean-Pierre Flourens. Unlike ether, chloroform's characteristically sweet odour isn't irritating, although inhalation of concentrated chloroform vapour may cause irritation of exposed mucous surfaces. Chloroform is a more effective anaesthetic than nitrous oxide.
In 1864, the Report of Chloroform Committee of Royal Medical and Chirurgical Society endorsed chloroform as Britain's favourite anaesthetic. But ether was safer for patients.
In 1871, leading anaesthetic manufacturer Edward E. Squibb of Brooklyn estimated [New York Medical Journal (April 1871) 13;389] that of 400,000 administrations of anaesthesia in the USA in 1870, chloroform was the agent used in some 50%, ether for 40%, and other gases and mixtures accounted for the rest.


Chloroform is a widely used industrial and laboratory solvent. It is a volatile chlorinated organic solvent whose vapors have a narcotic effect.Due to its light sensitivity, it may undergo degradation with time. This can be suppressed by adding ethanol as a stabilizer. The addition will increase the polarity of the solvent and potentially impact certain applications.
  1. Chloroform has been used as a solvent for dissolving lipids and also as a cleansing agent.
  2. It may also be used in solvent extraction process and also for recrystallization.
  3. Suitable for HPLC, spectrophotometry, environmental testing
  4. Facilitates recovery of the aqueous phase of PCRs which have been overlaid with mineral oil.
  5. Meets ACS specifications.


ChEBI: A one-carbon compound that is methane in which three of the hydrogens are replaced by chlorines.

General Description

A clear colorless liquid with a characteristic odor. Denser (12.3 lb / gal) than water and slightly soluble in water. Hence sinks in water. Nonflammable under most conditions, but burns under extreme conditions. May cause illness by inhalation, skin absorption or ingestion. Used as a solvent, to make other chemicals, as a fumigant.

Air & Water Reactions

Slightly soluble in water. Dissolves in water to form a corrosive solution of hypochlorous acid which decomposes on standing to chlorine, oxygen, and chloric acid.

Reactivity Profile

A mixture of acetone and Chloroform in a residue bottle exploded. Since addition of acetone to Chloroform in the presence of base will result in a highly exothermic reaction, Chloroform is thought that a base was in the bottle. [MCA Case History 1661(1970)]. Powdered aluminum and carbon tetrachloride(also methyl chloride and Chloroform or mixtures of these chemicals) exploded when heated(to 153°C.) and by impact, [Chem. Eng. News 32:258(1954); UL Bull. Research 34(1945), ASESB Pot. Incid. 39(1968)]. An inadequately cooled addition of sodium to a Chloroform-methanol mixture (sodium methoxide) caused a violent explosion, [MCA Case History No. 693]. Chloroform is incompatible with dinitrogen tetraoxide, fluorine, sodium metal and alcohols, nitromethane, and triisopropylphosphine.

Health Hazard

Chloroform is classified as moderately toxic. Probable oral lethal dose for humans is 0.5 to 5 g/kg (between 1 ounce and 1 pint) for a 150 lb. person. The mean lethal dose is probably near 1 fluid ounce (44 g). It is a human suspected carcinogen. Also, it is a central nervous system depressant and a gastrointestinal irritant. It has caused rapid death attributable to cardiac arrest and delayed death from liver and kidney damage.

Fire Hazard

Container may explode in the heat of fire. When heated Chloroform liberates phosgene, hydrogen chloride, chlorine and toxic and corrosive oxides of carbon and chlorine. Chloroform explodes when in contact with aluminum powder or magnesium powder or with alkali metals (e.g., lithium, sodium, and potassium) and dinitrogen tetroxide. Chloroform reacts vigorously with acetone in the presence of potassium hydroxide or calcium hydroxide. Chloroform is oxidized by strong oxidizers such as chromic acid forming phosgene and chlorine. Chloroform reacts vigorously with triisopropylphosphine. Chloroform develops acidity from prolonged exposure to air and light.
