る。[Problems 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 the generated chlorine radicals become 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.

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.

In addition, since it has extremely good azeotrope-like characteristics with the presence of an azeotropic point, there is little compositional variation during cycling, and it is the same as conventional single fluorocarbons (it can be used in different ways, requiring no major changes in conventional technology). It has the advantage that it can be applied as is without the need for
