Many of them are less toxic and chemically stable, and various types of chlorofluorocarbons with different standard boiling points are available. Taking advantage of these properties, 1,1,2-trichloro-1,2-trichloro-1,2 , 2-trifluoroethane (R113), trichloromonofluoromethane (R11) as a blowing agent, and dichlorodifluoromethane (R12) as a propellant or refrigerant.

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. In addition, in recent years, regulations have been advocated for its use due to environmental damage such as groundwater contamination and ozone layer depletion1, 1. It is also extremely useful as a substitute for l-)-lichloroethane. 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.

×: Significant residual [Effect of the invention] The azeotrope and azeotrope-like composition of the present invention have the conventional R113,
It can be used as a substitute substance while satisfying the excellent properties of 1,1,1-trichloroethane, and the composition change is small even when recycled, so it can be used as a substitute for 1,1,1-trichloroethane.
．． It has the advantage that it can be used in the same way as 1,1.1-trichloroethane alone and does not require major changes in conventional technology. Furthermore, as a solvent, it is excellent in removing flux, machine oil, etc., and is therefore most suitable as a flux removal solvent and a degreasing cleaning solvent in place of R113,1,1,1-trichloroethane.
