Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is chlorofluorocarbon. It is a colorless, nearly odorless liquid that boils at about room temperature. Its refractive index is 1.3821 (20 °C, D).
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 (1.0) of any refrigerant. U.S. production was ended in 1995.
Trichlorofluoromethane is used as a reference compound for fluorine-19 NMR studies.
