CLASSIFICATION

 

GENERAL DESCRIPTION

Trichloroethylene is a heavy, stable, toxic, nonflammable liquid with a chloroform aroma; boiling at 87 C; slightly soluble in water, soluble with greases and common organic solvents; Trichloroethylene is prepared by the chlorination of ethylene or ethylene dichloride. Because of concerns about its toxicity, the use is declining. It is prohibited to use in food, drugs and cosmetics. It is now mainly used in vapor degreasing of fabricated or assembling metal parts. It is also used as an industrial solvent in extraction processes, as a diluent in paints and adhesives, in textile processing, and other ways. It is used as a chain terminator for PVC production. It is also used as a refrigerant, as a heat exchange liquid, as a chemical intermediate or raw material in the production of chloroacetic acid, pesticides, gums, resins, tars, paints and varnishes. It is used in dry cleaning operations.

The production and use of 1,1,1-trichloroethane and carbon tetrachloride have been phased out throughout the world because of suspected harm to the earth's ozone layer.
