れている。[Prior art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are often non-toxic, non-flammable, and chemically stable, and various types of fluorocarbons with different standard boiling points are available. Various types of fluorocarbons are used as solvents, blowing agents, propellants, refrigerants, etc. For example, 1,1,2-trichloro-1,2,2-1- as a solvent
Lifluoroethane (R113) is used as a blowing agent, trichloromonofluoromethane (R11) is used as a blowing agent, and dichlorodifluoromethane (R12) is used as a propellant or refrigerant.

しにくい代替フロンの探索が活発に行なわれている。[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 the generated chlorine radicals become ozone. There is a movement to restrict the use of these conventional fluorocarbons because they are said to cause chain reactions and destroy the ozone layer. For this reason, the search for alternative fluorocarbons that are less likely to deplete the ozone layer is being actively conducted in place of these conventional fluorocarbons.
