trichloroethane
Also known as methylchloroform, 1,1,1-trichlorethane, alpha-T, methyltrichloromethane, alpha-trichloroethane, 1,1,1-TCE, trichloro-1,1,1-ethane
1,1,1-Trichloroethane, also known as methyl chloroform and chlorothene, is a chloroalkane with the chemical formula . It is an isomer of 1,1,2-trichloroethane. A colourless and sweet-smelling liquid, it was once produced industrially in large quantities for use as a solvent. It is regulated by the Montreal Protocol as an ozone-depleting substance, and as such, use has declined since 1996. Trichloroethane should not be confused with the similar-sounding trichloroethene which is also commonly used as a solvent.

==Production== 1,1,1-Trichloroethane was first reported by Henri Victor Regnault in 1840. Industrially, it is usually produced in a two-step process from vinyl chloride. In the first step, vinyl chloride reacts with hydrogen chloride at to produce 1,1-dichloroethane:
