METHOD FOR PRODUCING POROUS PARTICLE

摘要

In the present invention, a method for producing a porous particle is characterized by including: (1) a step of preparing a solution of an amphiphilic substance by dissolving an amphiphilic substance in a mixed solvent able to be freeze-dried; (2) a step of producing a precipitate containing the amphiphilic substance by cooling the solution obtained in step (1) to a temperature that is not higher than the phase separation temperature of the solution, and then holding the solution at this temperature; and (3) a step of producing a porous particle by freeze-drying the solution that contains the precipitate obtained in step (2).
