Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon. It is a colorless, nearly odorless liquid that boils at about room temperature.

[edit] Uses

It was the first widely used refrigerant. Because of its high boiling point (compared to most refrigerants), it can be used in systems with a low operating pressure, making the mechanical design of such systems less demanding than that of higher-pressure refrigerants R-12 or R-22.

Because of the high chlorine content and the ease with which the chlorine atoms can be displaced when the molecule is subject to ultraviolet light, R-11 has the highest ozone depletion potential of any refrigerant, by definition assigned the value 1.0. U.S. production was ended in 1995.

Trichlorofluoromethane is used as a reference compound for fluorine-19 NMR studies.
