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 they can be used to take advantage of these characteristics. Various fluorocarbons are used as solvents, blowing agents, propellants, refrigerants, etc.For example, 1,1,2-)cyclo-1,2,2-trifluoroethane (R113) is used as a blowing agent. Trichloromonofluoromethane (R11) is used as a propellant and dichlorodifluoromethane (R12) as a refrigerant.

にくい代替フロンの探索が活発に行なわれている。[Problems to be solved by the invention] R11, R12, and R113, which are particularly chemically stable, have a long life in the troposphere and diffuse into the stratosphere, where they are decomposed by sunlight and generated chlorine radicals. There is a movement to restrict the use of these conventional fluorocarbons because they are said to cause a chain reaction with ozone 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.

R113よりもフラックスや油等の溶解除去性に優れる
ためR113に替わる洗浄溶剤として好適である。[Effects of the Invention] The fluorinated hydrocarbon mixture of the present invention is nonflammable or flame retardant and can be used as a substitute for fluorocarbons while satisfying the excellent properties of conventional fluorocarbons, and has an azeotropic point. It has the advantages of no compositional changes during recycling, can be used in the same way as conventional single fluorocarbons, and does not require major changes to conventional technology. In addition, it is suitable as a cleaning solvent in place of R113 because it has better ability to dissolve and remove flux and oil than R113, which is often used as a solvent.
