れている。[Prior art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are mostly non-toxic, non-flammable, and chemically stable, and various fluorocarbons with different standard boiling points are available, so it is important to take advantage of these characteristics. 1,1,2-trichloro-1,2,2-trifluoroethane (R113) is used as a solvent, blowing agent, propellant, or refrigerant, and trichloromonofluoromethane (R11) is used as a blowing agent. Dichlorodifluoromethane (R12) is used as a refrigerant.

る。[Problem to be solved by the invention] R11, R12, and R113, which are particularly stable chemically, have a long life in the troposphere and diffuse into the stratosphere, where they are decomposed by sunlight and generate chlorine radicals, which are converted into ozone. Conventional regulations on the use of these fluorocarbons have been implemented because they are believed to cause a chain reaction and destroy the ozone layer. For this reason, there is active search for alternative fluorocarbons that are less likely to deplete the ozone layer in place of these conventional fluorocarbons.
