[Prior art] Fluorinated hydrocarbon compounds (hereinafter simply referred to as fluorocarbons) are mostly non-toxic, non-flammable, and chemically stable, and various types of fluorocarbons with different standard boiling points are available, so it is important to take advantage of these characteristics. Various types of fluorocarbons are used as solvents, blowing agents, propellants, refrigerants, etc. For example, 1.1.2-trichloro-1,2,2-trifluoroethane (R113) is used as a solvent, trichloromonofluoromethane (R11) is used as a blowing agent, and dichlorodifluoromethane (R12) is used as a propellant or refrigerant. It is used.

[Problem to be solved by the invention] Chemically particularly stable old 1. R12 and R113 have a long life in the troposphere and diffuse into the stratosphere, where they are decomposed by sunlight and generate chlorine radicals that cause a chain reaction with ozone and destroy the ozone layer. There is a movement to regulate the use of fluorocarbons. For this reason, the search for alternative fluorocarbons that are less likely to deplete the ozone layer is being actively conducted in place of these conventional fluorocarbons.

An object of the present invention is to provide a new fluorocarbon mixture that can be used as a fluorocarbon substitute while reducing the amount of conventional fluorocarbons used and satisfying the excellent properties of the fluorocarbons.

[Means for Solving the Problems] The present invention provides 2-trichlorofluoroethane (R113) and 1-chloropropane and ethanol.
The mixture of the present invention relates to a fluorinated hydrocarbon azeotrope-like mixture consisting of azeotropic mixtures of components.
Since it has higher cleaning power than that of R113 alone, it is extremely useful as a substitute for R113.
