专利说明:
[0001] The present invention relates to a carrier solvent comprising (perfluorohexyloxy)methane and/or tridecafluorohexane, which is useful as a carrier solvent for various organic chemical substances such as a lubricant, a coating material, a mold release agent, a water/oil repellent, an oil or a grease. [0001]
[0002] Heretofore, as carrier solvents for various organic chemical substances, trichlorotrifluoroethane (hereinafter referred to as R[0002] 113), dichloropentafluoropropane (hereinafter referred to as R225) and perfluorocarbons (hereinafter referred to as PFC) such as perfluorohexane, which are excellent in non-flamability and chemical and thermal stability, have been widely used.
[0003] However, they respectively have adverse effects on the global environment, such that R[0003] 113 and R225 have an ozone-depletion potential, and PFC has a very high global warming potential. Production of chlorofluorocarbons such as R113 has already been prohibited, and in developed countries, hydrochlorofluorocarbons such as R225 are phase out by 2020. Further, PFC is listed as a substance subject to regulation by the Kyoto Protocol for preventing global warming. It is an object of the present invention to provide a carrier solvent which has a performance equal to such R113, R225 or PFC and which has little adverse effect on the global environment.
[0004] As a result of extensive studies, the present inventors have found that a fluorinated solvent comprising, as an effective component, a fluorinated solvent (hereinafter referred to as a fluorinated solvent A) selected from the group consisting of (perfluorohexyloxy)methane and tridecafluorohexane, can be used as a carrier solvent. [0004]
[0005] Namely, the present invention provides a method for dissolving an organic chemical substance with a carrier solvent, wherein the carrier solvent comprises at least one fluorinated solvent A selected from the group consisting of (perfluorohexyloxy)methane and tridecafluorohexane. [0005]
[0006] Further, the present invention provides a composition comprising an organic chemical substance and at least one fluorinated solvent A selected from the group consisting of (perfluorohexyloxy)methane and tridecafluorohexane. [0006]
