1-chloro-1,2,2,2-tetrafluoroethane is a chemical compound from the group of partially halogenated chlorofluorocarbons (CFCs) that was used as a refrigerant and propellant . It is considered harmful to the ozone layer . It replaces R-114 or dichlorotetrafluoroethane as a refrigerant in refrigeration machines for high ambient temperatures.
properties
1-chloro-1,2,2,2-tetrafluoroethane has an ozone depletion potential of 0.03.
safety instructions
As with all CFCs, the thermal decomposition (through intense heat) of chlorotetrafluoroethane forms corrosive substances ( hydrochloric acid , hydrofluoric acid ).
