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 cause a chain reaction and destroy ozone waste. For this reason, the search for alternative fluorocarbons that are less likely to destroy ozone dust is being actively conducted in place of these conventional fluorocarbons.

ある。[Effects of the Invention] The fluorinated hydrocarbon composition of the present invention has properties equivalent to or superior to those of conventional fluorocarbons. It also has the advantage of having an azeotropic point, having little compositional variation during recycling, and can be used in the same way as conventional single fluorocarbons, and can be applied as is without requiring major changes to conventional technology.
