CLASSIFICATION

 

GENERAL DESCRIPTION

1,1,2-Trichloroethane (also called Vinyl trichloride) is a family of halogenated hydrocarbons compund used as a solvent and chemical intermedaite. It is a manufactured chemical that does not occur naturally. It is a colorless liquid with a sharp, sweet odor like ether. It is insoluble in water, but miscible with other chlorinated solvents and soluble in alcohols, ethers, esters, and ketones. It should be handled with cautions. It evaporates quickly and becomes a vapor, though 1,1,2-Trichloroethane exists in the form of a liquid. It forms hydrogen chloride, phosgene,carbon monoxide and other toxic gases when it contacts with hot surfaces or flames. It reacts with strong oxidizers, strong bases and chemically-active metals such as sodium, potassium, magnesium and powdered aluminium. It attacks many plastics, rubber, steel and zinc.

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.
