More specifically, flux cleaning, degreasing cleaning, draining drying,
The present invention relates to a composition used as a solvent or the like. Conventionally, halogenated hydrocarbons are most well known as solvents for cleaning electronic parts, precision machine parts, resin processed parts, etc., and chlorine atoms or chlorine atoms and fluorine atoms are known. It has the characteristics as a substituted hydrocarbon group. These halogenated hydrocarbons are less toxic,
When the number of halogen substitutions is large, it exhibits nonflammability, is chemically and thermally stable, and has moderate solubility that dissolves waxes and fats and oils without eroding the surface of plastics and rubber. Therefore, it is widely used in various industrial fields. For example, these halogenated hydrocarbons include chlorinated hydrocarbons such as trichloroethylene, tetrachloroethylene, 1,1,1-trichloroethane, 1,1,2-trichloro-1,2,2-trifluoroethane (Freon 113), and the like. In particular, the latter fluorocarbons are used in a wide range of fields because they are less toxic, nonflammable, and chemically and thermally stable. However, since chlorofluorocarbons and 1,1,1-trichloroethane containing chlorine have chlorine atoms, a serious disadvantage of destroying the stratospheric ozone layer has been pointed out, and it is Is decided. In addition, trichlorethylene and tetrachlorethylene have been declared ordinances for Class 2 Specified Chemical Substances since 1989, based on the results of a survey on the groundwater contamination problem, the subsequent environmental pollution status survey results, and chronic toxicity. Designated. Under such circumstances, development of a substitute for such a chlorofluorocarbon containing chlorine and a chlorinated hydrocarbon has been actively conducted. SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and has excellent detergency, low toxicity, etc. possessed by chlorofluorocarbon-containing hydrocarbons and chlorine-containing hydrocarbons. Without damaging the properties, there is no worry of ozone depletion,
In addition, it is an object to provide a novel composition having a small greenhouse effect. As a result of intensive studies to solve the above-mentioned problems, the present inventors have completed the present invention. That is, according to the present invention, 1,1,2,2-tetrafluoro-3- 1 represented by the following formula (1) CHF 2 CF 2 CH 2 OCF 2 CHF 2 (1)

The content of alcohols in the composition of the present invention is 1 to 50% by weight in the total solvent. Since the alcohols in the composition are flammable compounds, it is not preferable because the flammability of the solvent increases when the content is more than the above range, while when the content is less than the above range,
Since the effect of addition becomes insufficient, it is not preferable. The azeotropic composition in the present invention means that the vapor composition and the liquid composition are the same, and the composition does not change after repeated evaporation and condensation. The azeotrope-like composition means that the vapor composition and the liquid composition are almost the same, and the composition change of the composition after repeated evaporation and condensation changes only to a negligible level. An azeotrope-like composition of the invention,
Specifically, the azeotropic composition has the following composition. (1) 1,1,2,2-tetrafluoro-3- (1,
1,2,2-tetrafluoroethoxy) -propane 50

Further, in order to obtain a synergistic stabilizing effect, phenols, amines and benzotriazoles may be used in combination. These stabilizers may be used alone or in combination of two or more. The amount of stabilizer used varies depending on the type of stabilizer and the like, but does not interfere with the azeotropic properties. The amount used is usually about 0.01 to 10% by weight of the composition of the present invention, more preferably about 0.1 to 5% by weight.

For the purpose of synergistically improving detergency and interfacial action, a cationic surfactant or an anionic surfactant may be used in combination with these nonionic surfactants. The amount of the surfactant used varies depending on the type and the like, but is usually 0.1% of the composition of the present invention as long as the azeotropic properties are not hindered.
About 20% by weight, and more preferably about 0.3-5% by weight. The composition of the present invention can be widely used for known cleaning and drying applications. In particular, it can be used as a flux cleaning agent, a cleaning solvent, a degreasing cleaning agent, and a draining drying agent. It is extremely useful as a substitute for 1-trichloroethane.
