tetrachloroethane tet·ra·chlo·ro·eth·ane (tět'rə-klôr'ō-ěth'ān')
A toxic, nonflammable solvent used in the manufacture of paint and varnish removers, photographic films, lacquers, and insecticides.
either of two isomeric colourless, dense, water-insoluble liquids belonging to the family of organic halogen compounds. One isomer, 1,1,2,2-tetrachloroethane, also called acetylene tetrachloride, is highly toxic. Almost the entire production of the compound is consumed in manufacturing chlorinated solvents, especially trichloroethylene and tetrachloroethylene; it has minor uses as a solvent and as an insecticide, particularly against the greenhouse white fly. It is made by the reaction of acetylene and chlorine. The other isomer, 1,1,1,2-tetrachloroethane, has no commercial application
