る。[Problem to be solved by the invention] R11, R12, and R113, which are chemically stable, have a long life in the troposphere and diffuse into the stratosphere, where they are decomposed by sunlight and generate chlorine radicals. Conventional regulations on the use of these fluorocarbons have been implemented because they cause a chain reaction with ozone 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.

225cb) and 2-bromopropane The composition of the present invention has an azeotropic composition, and in particular, as a cleaning solvent, conventional R113 Since it has higher detergency than that of a single substance, it is extremely useful as a substitute for R113.
