| Use Information |
1,1,2,2-Tetrachloroethane (C.A.S. 79-34-5) is a man-made colorless or pale yellow dense liquid with a penetrating, sweet chloroform-like odor. The only major use for it is as a feedstock in the production of trichloroethylene, tetrachloroethylene, and 1,2-dichloroethylene. It may also be used as a solvent; in cleaning and degreasing metals; in paint and rust removers, varnishes and lacquers; in photographic films; and as an extractant for oils and fats. Although 1,1,2,2-tetrachloroethane may be used as an insecticide, fumigant, and weedkiller, it presently is not registered for any of those purposes. It was once an ingredient in an insect repellent, but registration was cancelled in the late 1970s. Due to its toxicity and new processes for manufacturing chlorinated ethylenes, the manufacture and use of 1,1,2,2-tetrachloroethane now appears to be very limited. Information about the chemical is proprietary; therefore, it is not known specifically where it is used, or in what products it is found. Patterns of its use can best be determined from surveys of industrial wastewater. |
