れている。[Prior art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are mostly non-toxic and chemically stable, and various types of fluorocarbons with different standard boiling points can be produced by hand.Using these properties, they can be used as 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 blowing agent, propellant, or refrigerant. Dichlorodifluoromethane (R12') is used.

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. Conventional regulations on the use of these fluorocarbons have been implemented because they are believed to cause a chain reaction and destroy the ozone layer. 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.
本発明は、従来のフロンと同等な種々の優れた特性を有

The present invention relates to fluorinated hydrocarbon azeotropic and azeotrope-like compositions consisting of hydrocarbon mixtures. The composition of the present invention comprises:
Azeotropic compositions exist, especially conventional R113 as a cleaning solvent.
Since it has the same detergency as that of the simple substance, it is extremely useful as a substitute for R113.
更に、共沸組成と異なった組成においても、極めて組成
変化の少ない良好な共沸様特性を示し、このため、リサ
イクルしても組成の変動が少ないこと、又従来の単一フ

ないこと等の利点がある。Furthermore, it exhibits good azeotrope-like characteristics with very little compositional change even in compositions different from the azeotropic composition, so there is little change in composition even when recycled, and it can be used in the same way as conventional single CFCs. It has the advantage that it does not require major changes to the conventional technology.
