1,1,2,2-Tetrachloroethane (TeCA), also known as acetylene tetrachloride and by the brand names Bonoform, Cellon and Westron, is an organochloride. It is a dense, colorless, non-flammable liquid with a sweet odor, used as an industrial solvent and as a separation agent. TeCA is toxic to humans via inhalation, ingestion and skin absorption. After exposure, nausea, dizziness or liver damage may occur.
