  • Various oils, including lubricating oils, such as silicone oil, fluorine-based oil, mineral-based oil, grease, and wax, are used for various applications. These oils can be singly applied to substrate surfaces or machine part surfaces in need of lubrication; however, in consideration of predetermined necessity or purpose, they are often used after being dissolved in solvents. For example, these oils are used when it is necessary to adjust viscosity etc., or used for the purpose of forming lubricating films of the oils on the surfaces to which the oils are applied.
  • Moreover, those that have the same composition as these solvents and that are used to dissolve various oils for cleaning are particularly called detergents, cleaning solvents, etc.
  • Some solvents or detergents are required to be non-flammable. Conventionally used non-flammable solvents are fluorine-based solvents with low toxicity, represented by trade names “Asahilkin AK-225,” “Zeorola H,” “Novec,” etc.
  • However, it is indicated that these conventional fluorine-based solvents or detergents, which are advantageous in non-flammability and low toxicity, have problems in terms of environmental destruction, such as possibility of ozone layer depletion and possibility of contribution to global warming. In consideration of these circumstances, products, such as various hydrofluoroolefins and 1,2-dichloroethylene, have been developed as environmentally friendly solvents. Examples include chlorofluoroolefin (boiling point: 46° C.) (PTL 1), hydrochlorofluoroolefin (boiling point: 53° C.) (PTL 2), 1,2-dichloroethylene (boiling point: 48° C.), a mixture of 1,2-dichloroethylene and hydrofluoroolefin mentioned above, and cyclic hydrofluorocarbon (boiling point; 83° C.) (PTL 3), and the like.
  • In contrast, however, these environmentally friendly solvents have various problems such that they have low solubility; the solvents themselves are flammable; when they are mixed with second non-flammable solvents to reduce the flammability of the solvents themselves, it is necessary to adjust the composition ratio so that the mixed solvents are azeotropic; their boiling point is not suitable; and reduction in the global warming potential is not sufficient.
