ものである。[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. There is a movement to restrict the use of these conventional fluorocarbons because they cause a chain reaction and destroy the ozone layer. For this reason, active efforts are being made to find alternative fluorocarbons that are less likely to deplete the ozone layer in place of these conventional fluorocarbons. An object of the present invention is to provide a new fluorocarbon mixture that can be used as a fluorocarbon substitute while reducing the amount of conventional fluorocarbons used and satisfying the excellent properties of the fluorocarbons.
