Bromoform Chemical Properties,Uses,Production

Chemical Properties

Bromoform is a colorless to pale yellow liquid with a high refractive index, very high density, and sweetish odor is similar to that of chloroform. It is slightly soluble in water and is nonflammable. Bromoform can form in drinking water as a by-product from the reaction of chlorine with dissolved organic matter and bromide ions.


  1. In separating mixtures of minerals. Bromoform is used as a fluid for mineral ore separation in geological tests, as a laboratory reagent, and in the electronics industry in quality assurance programs.
  2. Bromoform was formerly used as a solvent for waxes, greases, and oils, as an ingredient in fire-resistant chemicals and in fluid gauges. It was also used in the early part of this century as a medicine to help children with whooping cough get to sleep. Currently, bromoform is only produced in small amounts for use in laboratories and in geological and electronics testing.

General Description

A colorless liquid with a chloroform-like odor. Denser than water (density: 2.9 g / cm3 ) and slightly soluble in water. Hence sinks in water. Nonflammable. Toxic by ingestion, inhalation and skin absorption. A lachrymator. Used as a solvent and to make pharmaceuticals. Often stabilized with 1 to 3% ethanol.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

Heating Bromoform to decomposition produces highly toxic fumes of carbon oxybromide (carbonyl bromide) and hydrogen bromide [Sax, 9th ed., 1996, p. 519]. Reaction with powdered potassium or sodium hydroxide, Li or Na/K alloys, is violently exothermic [Weizmann, C. et al., J. Am Chem. Soc., 1948, 70, p. 1189]. Explosive reaction with crown ethers in the presence of potassium hydroxide [Le Goaller, R. et al., Synth. Comm., 1982, 12, p. 1163].


A questionable carcinogen. By ingestion, inhalation, and skin absorption. Liver damage, eye and upper respiratory tract irritant.

Health Hazard

Probable routes of human exposure to bromoform are inhalation, ingestion, and dermal contact.
Harmful if inhaled, swallowed, contacts skin or eyes or is absorbed through skin. It is a lachrymator, respiratory irritant, a narcotic and an hepatotoxin. Prolonged exposure may cause dermatitis. Inhalation causes irritation of nose and throat; provokes the flow of tears and saliva and reddening of the face. Ingestion may cause dizziness, disorientation and slurred speech, unconsciousness and death.
Non-Cancer: Bromoform is a central nervous system depressant, and its vapors are highly irritating to the eyes and respiratory tract. Limited observations in humans and animal studies indicate that acute inhalation or oral exposure to high levels of bromoform may cause liver and kidney injury. Chronic effects of bromoform exposure in humans have not been studied, although animal studies indicate adverse effects on the liver, kidney, and central nervous system (U.S. EPA, 1994a).

Fire Hazard

Behavior in Fire: May decompose to produce toxic gases and vapor such as hydrogen bromide and bromine.

Safety Profile

Suspected carcinogen with experimental neoplastigenic data. A human poison by ingestion. Moderately toxic by intraperitoneal and subcutaneous routes. Human mutation data reported. A lachrymator. It can damage the liver to a serious degree and cause death. It has anesthetic properties simdar to those of chloroform, but is not sufficiently volatile for inhalation purposes and is far too toxic for human use. As a sedative and antitussive its medicinal application has resulted in numerous poisonings. Inhalation of small amounts causes irritation, provoking the flow of tears and saliva, and reddening of the face. Abuse can lead to adhction and serious consequences. Explosive reaction with crown ethers or potassium hydroxide. Violent reaction with acetone or bases. Incompatible with Li or NaK alloys. When heated to decomposition it emits hghly toxic fumes of Br-. See also BROMIDES.

Purification Methods

The storage and stability of bromoform and chloroform are similar. Ethanol, added as a stabilizer, is removed by washing with H2O or with saturated CaCl2 solution, and the CHBr3, after drying with CaCl2 or K2CO3, is fractionally distilled. Prior to distillation, CHBr3 has also been washed with conc H2SO4 until the acid layer is no longer coloured, then dilute NaOH or NaHCO3, and H2O. A further purification step is fractional crystallisation by partial freezing. [Beilstein 1 IV 82.]
