RECOVERY METHOD OF TARGET SUBSTANCE FROM SOLUTION

摘要

PROBLEM TO BE SOLVED: To provide a recovery method of a target substance (A) from a solution (C) which is composed of a target substance (A) to be recovered and a first solvent (B) capable of recovering the target substance from the solution without being indispensable of heating the solution such as a distillation and thus capable of recovering the target substance which is unstable to the heat without deterioration and excellent in aspect of energy saving. SOLUTION: This is a recovery method of a target substance (A) from a solution (C) which includes the first process and the second process below. The first process comprises forming an emulsion (E) comprising the target substance (A) and the second solvent (D) by adding and mixing the second solvent (D) to the solution (C). The second process comprises separating the emulsion (E) obtained in the first process from the solvent (C). COPYRIGHT: (C)2005,JPO&NCIPI
