Method and apparatus for solution/separation at predetermined temperature with solvent set undergoing temperature-dependent reversible change between solution phase and separation phase

摘要

A method for solution/separation phase change at a constant temperature (with no temperature change) in a combination of a first solvent and a second solvent of a mixture of plural solvents that undergoes temperature-dependent reversible change between solution phase and separation phase. A method for solubilization or phase separation of first and second solvents at a constant temperature by adding thereto a solvent that constitutes the first solvent and/or the second solvent, on the basis of the solution/separation temperature data relative to the blend ratio of the first and second solvents and the composition blend ratio of the second solvent in the solvent set that is in a separation phase, in such a manner that the first and second solvents may have a blend ratio at which they may undergo solution/separation phase change at a temperature lower than the temperature of the separation-phase solvent set.
