carbon tetrachloride

a colorless, nonflammable, vaporous, toxic liquid, CCl4, usually produced by the reaction of chlorine with carbon disulfide, methane, or other carbon-containing compounds: used mainly as a refrigerant, fire extinguisher, cleaning fluid, solvent, and insecticide. Also called tetrachloromethane, perchloromethane.
[1900-05]

also called  tetrachloromethane 

      a colourless, dense, highly toxic, volatile, nonflammable liquid possessing a characteristic odour and belonging to the family of organic halogen compounds, used principally in the manufacture of dichlorodifluoromethane (a refrigerant and propellant).

      First prepared in 1839 by the reaction of chloroform with chlorine, carbon tetrachloride is manufactured by the reaction of chlorine with carbon disulfide or with methane. The process with methane became dominant in the United States in the 1950s, but the process with carbon disulfide remains important in countries where natural gas (the principal source of methane) is not plentiful. Carbon tetrachloride boils at 77° C (171° F) and freezes at -23° C (-9° F); it is much denser than water, in which it is practically insoluble.

      Formerly used as a dry-cleaning solvent, carbon tetrachloride has been almost entirely displaced from this application by tetrachloroethylene, which is much more stable and less toxic.
