いる。[Prior art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are
Many of them are less toxic and chemically stable, and various types of fluorocarbons with different standard boiling points are available. Taking advantage of these characteristics, they can be used as solvents, blowing agents, propellants, refrigerants, etc. 1,2-trichloro-1,2,2,-trifluoroethane (R113), trichloromonofluoromethane (R11) as a blowing agent, and dichlorodifluoromethane (R12) as a propellant or refrigerant.

ら従来のフロンの使用規制が実施されることとなった。[Problem 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 generate chlorine radicals, which are then combined with ozone. Conventional regulations on the use of these fluorocarbons have been implemented because they are believed to cause chain reactions and destroy the ozone layer.

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

The present invention relates to a fluorinated hydrocarbon azeotrope-like composition comprising methylbencune and/or 3-methylpentane, and a mixture thereof with either methanol or ethanol. The composition of the present invention has the advantage that there is little change in composition even when recycled, and since it can be used in the same way as conventional single fluorocarbons, it does not require major changes to the conventional technology. In particular, as a cleaning solvent, R113 has higher cleaning power than conventional R113 alone.
It is extremely useful as an alternative to 113.

超音波洗浄、蒸気洗浄等を採用すればよい。The composition of the present invention, like conventional fluorocarbons, can be used for various purposes such as heat carriers and blowing agents, and is particularly suitable when used as a solvent because it has a higher dissolving power than conventional R113. Specific uses of solvents include removers for flux, grease, oil, wax, and ink, paint solvents, extractants, glass, ceramics, plastics, rubber, various metal products, especially IC parts, electrical equipment, Examples include cleaning agents and draining agents for precision instruments, optical lenses, etc. Cleaning methods include hand wiping, dipping, spraying, shaking,
Ultrasonic cleaning, steam cleaning, etc. may be used.
