chloroform (redirected from chloroforms)

chloroform (klôr`əfôrm) or trichloromethane (trī'klôrōmĕth`ān), CHCl₃, volatile, colorless, nonflammable liquid that has a sweetish taste and a somewhat pungent odor; it boils at 61.7°C;. It dissolves freely in ethanol and ether but does not mix with water. Chloroform is produced by reaction of chlorine with ethanol and by the reduction of carbon tetrachloride with moist iron. It was once used as a general anesthetic in surgery but has been replaced by less toxic, safer anesthetics, such as ether. Chemically, it is employed as a solvent for fats, alkaloids, iodine, and other substances. When exposed to sunlight and air it reacts to form phosgene, a poisonous gas.

chloroform

Clear, colourless, heavy, nonflammable liquid organic compound with a pleasant etherlike odour, chemical formula CHCl₃. It was the first substance successfully used as a surgical anesthetic (1847); being somewhat toxic, it has been increasingly displaced by other substances for this purpose. It has some industrial uses, primarily as a solvent.
