PROCESS FOR PRODUCING COATED COMPOSITE SUBSTANCE UTILIZING LIQUID-LIQUID INTERFACE

摘要

Disclosed is a process for producing a coated composite substance under mild conditions by a simple process. The process is characterized by: preparing a solution (A') which comprises a solvent (A) and a solute (S) dissolved in the solvent (A) at a high concentration, a solvent (B) which has an affinity for the solvent (A) but has poor miscibility with the solvent (A) and cannot substantially dissolve the solute (S), and a carrier (C) which cannot be dissolved in either the solvent (A) or the solvent (B); coating the surface of the carrier (C) with the solution (A'); and bringing the coated surface of the carrier (C) into contact with the solvent (B) to cause the solute (S) to be crystallized on the surface of the carrier (C).
