Abstract
(Purpose) Providing a solvent set preferable for use as miscible-multiphase organic solvent system. While the miscible temperature of a solvent system is dropped by using a mixture solvent of plural solvents in the related art, the temperature can be dropped by a single solvent. Providing a solvent set appropriate for chemical processes imparted electric energy, such as electrochemical process. (Means for Resolution) Use of a chemical process using a combination of a first solvent and a second solvent, where the miscible state and the separation state reversibly change depending on the temperature, where the first solvent includes an alkane-series compound and/or a cycloalkane-series compound; and the second solvent includes at least one selected from the group consisting of a carbonate (carboxylic acid ester) compound, a carbamate (urethane) compound, an urea compound, a cyclic amide compound and a cyclic ketoamine compound.
