いる。[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 and replace these 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.
