る。[Problems to be Solved by the Invention] Chemically particularly stable R11, R12, and R113 have a long life in the troposphere, reach the stratosphere by diffusion, and chlorine radicals generated by decomposition by solar rays are ozone. There is a movement to regulate the use of these conventional CFCs because they cause a chain reaction with and destroy the ozone layer. For this reason, in place of these conventional CFCs, the search for CFC alternatives that are less likely to destroy the ozone layer is being actively carried out. An object of the present invention is to provide a novel mixture of fluorocarbons which can be used as a substitute fluorocarbon while reducing the amount of conventional fluorocarbon and satisfying the excellent characteristics of the fluorocarbon.
