Dichlorofluoromethane is a chemical compound from the group of aliphatic, saturated chlorofluorocarbons, hydrocarbons.

Properties

The density of the liquid phase at the boiling point of dichlorofluoromethane is 1.4048 kg / l at 1 bar and 15 ° C. The critical temperature is 178.5 ° C, the critical pressure is 51.7 bar, the critical density of 0.522 g/cm3, the triple point is the temperature -135 ° C ( melting temperature). Dichlorodifluoromethane is listed in the Montreal Protocol and ozone depletion potential is 0.040.

Use

Dichlorodifluoromethane was used in refrigeration as refrigerants and as inert propellant for aerosols and foams. Today, the use is prohibited due to the ozone depletion potential.
