1,1,2-Trichloroethane
Template:Chembox 1,1,2-Trichloroethane, vinyl trichloride or 1,1,2-TCA, is an organochloride solvent with the molecular formula Template:Chem2 and the structural formula Template:Chem2. It is a colourless, sweet-smelling liquid that does not dissolve in water, but is soluble in most organic solvents. It is an isomer of 1,1,1-trichloroethane, and a byproduct of its manufacture.
It is used as a solvent and as an intermediate in the synthesis of 1,1-dichloroethylene.[1]
Toxicity
1,1,2-Trichloroethane may be harmful by inhalation, ingestion, and skin contact. It is a respiratory and eye irritant. 1,1,2-TCA is a central nervous system depressant and inhalation of vapors may cause dizziness, drowsiness, headache, nausea, shortness of breath, and unconsciousness.[2]
The Occupational Safety and Health Administration and National Institute for Occupational Safety and Health have set occupational exposure limits to 1,1,2-trichloroethane at 10 ppm over an eight-hour time-weighted average.[3]
