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 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 in place of these conventional fluorocarbons.

剤として最適である。Table 2 [Effects of the Invention] The fluorinated hydrocarbon solvent composition of the present invention can be used as a fluorocarbon substitute while satisfying the excellent properties of conventional fluorocarbons, and does not change its composition even when recycled. Because it is small, it can be used in the same way as a conventional single fluorocarbon, and has the advantage of not requiring major changes to the conventional technology. In addition, it has better ability to dissolve and remove flux, oil, etc. than R113, which is often used as a solvent, so it is most suitable as a cleaning solvent in place of R113.
