る。[Prior Art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are often less toxic and chemically stable, and various types of fluorocarbons with different standard boiling points are available.Using these characteristics, they can be used as solvents, 1,1,2-trichloro-1,2,2-trifluoroethane (R113) is used as a blowing agent, propellant, or refrigerant, trichloromonofluoromethane (R11) is used as a blowing agent, and dichlorodifluoro is used as a propellant or 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. Because of this, the search for alternative fluorocarbons that are less likely to deplete the ozone layer is being actively conducted in place of these conventional fluorocarbons.
