にくい代替物質の探索が活発に行なわれている。[Problems to be solved by the invention] When fully halogenated hydrocarbons such as CFCs R11, R12, and R113, which are particularly chemically stable, reach the stratosphere, chlorine radicals decomposed by sunlight cause a chain reaction with ozone. Since these substances are believed to destroy the ozone layer, regulations have been implemented on the production of these specific fluorocarbons. Therefore, in place of these conventional fluorocarbons, there is active search for alternative substances that are less likely to deplete the ozone layer.

It is extremely useful as a substitute for No. 13. It is also extremely useful as a substitute for 1,1°1-trichloroethane, whose use has been regulated in recent years due to environmental damage such as groundwater contamination and ozone layer destruction. Furthermore, it has the advantage that there is little change in composition even after recycling, and that it can be used in the same manner as conventional single fluorocarbons, and does not require major changes in conventional technology.
