Trichlorofluoromethane, also called freon-11, CFC-11, or R-11, is a chlorofluorocarbon. It is a colorless, faint ethereal and sweetish odor liquid that boils at about room temperature.

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.

R-11 is assigned an ozone depletion potential of 1.0. U.S. production was ended in January 1, 1996.

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

Prior to the knowledge of the ozone depletion potential of chlorine in refrigerants and other possible harmful effects on the environment, trichlorofluoromethane was sometimes used as a cleaning/rinsing agent for low pressure systems.
