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. 1.2 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.

ロンに変わり、オゾン層を破壊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 generate chlorine radicals, which are converted into ozone. Due to the fact that they cause a chain reaction and destroy the ozone layer, the previous regulations on the use of these fluorocarbons have been implemented. 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.

It relates to fluorinated hydrocarbon azeotropes and azeotrope-like mixtures. The mixture of the present invention is nonflammable, has an azeotropic composition, and has higher detergency as a cleaning solvent than conventional R113 alone, so it is extremely useful as a substitute for R113.

Furthermore, since it has an azeotropic point, there is no change in composition during recycling, and it can be used in the same way as conventional single chlorofluorocarbons, which has the advantage of being able to be applied as is without requiring major changes to the conventional technology.
又、溶剤としてよく使われているＲ１１３単体よりも、
フラックスや油等の溶解除去性に唆れるためＲ１１３に
替わる洗浄溶剤として好適である。In addition, compared to R113 alone, which is often used as a solvent,
It is suitable as a cleaning solvent in place of R113 because of its ability to dissolve and remove flux, oil, etc.
