GENERAL DESCRIPTION & APPLICATIONS

1,1,1-Trichloroethane or methylchloroform is a family of halogenated hydrocarbons compound used as a solvent or degreaser. 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 in common organic solvents. It should be handled with cautions. It evaporates quickly and becomes a vapor, though 1,1,1-Trichloroethane exists in the form of a liquid. It can be dissolved to varying amounts in water, food, and other chemicals. If heated to decomposition or on contact with acids or acid fumes, it evolves highly toxic chloride fumes. It reacts slowly with water to form hydrochloric acid. It is reactive with strong caustics; strong oxidizers; and chemically-active metals. It was widely used as a solvent and as chemical intermediate. But 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.
