1,1,2-Trichloroethane, vinyl trichloride or 1,1,2-TCA, is an organochloride solvent with the molecular formula C 2 H 3 Cl 3 and the structural formula CH 2 Cl—CHCl 2. It is a colourless , sweet-smelling liquid that does not dissolve in water , but is soluble in most organic solvents .
The organic compound 1,1,1-trichloroethane, also known as methyl chloroform and chlorothene, is a chloroalkane with the chemical formula CH 3 CCl 3. 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. [5]
1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane (often abbreviated as TCTFE) or CFC-113, is a chlorofluorocarbon. It has the formula Cl 2 FC−CClF 2 . This colorless, volatile liquid is a versatile solvent.
Via several steps, 1,2-dichloroethane is a precursor to 1,1,1-trichloroethane. Historically, before leaded petrol was phased out, chloroethanes were used as an additive in petrol to prevent lead buildup in engines.
HC≡CH + 2 Cl 2 → Cl 2 CHCHCl 2. The 1,1,2,2-tetrachloroethane is then dehydrochlorinated to give trichloroethylene. This can be accomplished either with an aqueous solution of calcium hydroxide: 2 Cl 2 CHCHCl 2 + Ca(OH) 2 → 2 ClCH=CCl 2 + CaCl 2 + 2 H 2 O. or in the vapor phase by heating it to 300–500 °C on a barium chloride or ...
Trichloroethane (C 2 H 3 Cl 3) may refer to either of two isomeric chemical compounds: 1,1,1-Trichloroethane (methyl chloroform, CCl 3 CH 3) 1,1,2-Trichloroethane ...
1,1,2,2-tetrachloroethane was used in large amounts to produce other chemicals like trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. [6] Because of its possible carcinogen effects on humans, the production of 1,1,2,2-tetrachloroethane has decreased significantly and is no longer widely used as an end-product. [7]
