れている。[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, so these characteristics can be utilized to develop solvents. , 1.1.2-)dichloro-1,2,2-trifluoroethane (R113) is used as a blowing agent, propellant, or refrigerant, and trichloromonofluoromethane (R11) is used as a propellant or refrigerant. Dichloromethane (R1,2') is used.

いる。[I1 Problem to be solved by the invention] R11, R12, and R113, which are particularly stable chemically, have a long life in convection and diffuse into the stratosphere, where they are decomposed by sunlight and generate chlorine radicals. Because it causes a chain reaction with ozone2 and destroys the ozone layer,
These conventional regulations on the use of fluorocarbons have now 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.

The present invention relates to fluorinated hydrocarbon azeotropic and near-azeotropic compositions consisting of a mixture of hydrocarbons having 5 to 8 carbon atoms and having as a main component. The composition of the present invention also has an azeotropic composition and has a cleaning power comparable to that of conventional R113 (substrate), especially when used as a cleaning solvent. It is extremely useful as a substitute for R113.

It has the advantage that it does not require major changes to the conventional technology.

［発明の効果］
本発明のフッ素１ヒ炭化水素系組成物は、従来のフロン
類が有している優れた特性と同等以上の特性を有する。[Effects of the Invention] The fluorine-monocarbon hydrocarbon composition of the present invention has properties equivalent to or superior to those of conventional fluorocarbons.
又、共沸点が存在する、極めて良好な擬共沸特性を有す
るなめ、リサイクル時に組成変動が少なく、従来の単一
フロンと同じ使い方ができ、従来技術の大幅な変更を必
要とせず、そのまま適用できる等の利点がある。In addition, because it has an azeotropic point and has extremely good quasi-azeotropic properties, there is little change in composition during recycling, and it can be used in the same way as conventional single fluorocarbons, so it can be applied as is without the need for major changes to conventional technology. There are advantages such as being able to
