The rise of gas anaesthesia using nitrous oxide, improved equipment for administering anaesthetics and the discovery of hexobarbital in 1932 led to the gradual decline of chloroform narcosis. [14], As chloroform is a volatile organic compound,[15] it dissipates readily from soil and surface water and undergoes degradation in air to produce phosgene, dichloromethane, formyl chloride, carbon monoxide, carbon dioxide, and hydrogen chloride. WebPhysical Properties. [citation needed], On 4 November 1847, Simpson first discovered the anaesthetic qualities of chloroform on humans.

Chloroform is used as a heat transfer medium in fire extinguishers, where it lowers the temperature of carbon tetrachloride. Results of studies of people who drank chlorinated water showed a possible link between the chloroform in chlorinated water and the occurrence of cancer of the colon and urinary bladder. Chloroform is a transparent liquid having a slightly sweet taste and an ether-like odour. However, most of the chloroform found in the environment is produced by humans.
