Chloropentafluoroethane is a chemical compound from the group of fully halogenated chlorofluorocarbons (CFCs) that was used as a refrigerant and propellant . It is considered harmful to the ozone layer .

properties

Chloropentafluoroethane is a colorless, odorless (in higher concentrations a sweet, ethereal odor) gas. It decomposes when heated to a great extent, which can produce halogen compounds such as hydrogen chloride and hydrogen fluoride, as well as dioxins . Chloropentafluoroethane has a heat capacity of 0.116 kJ / (mol K).

safety instructions

As with all CFCs, the decomposition (through intense heat) of chloropentafluoroethane forms corrosive substances ( hydrochloric acid , hydrofluoric acid ).
