Kind Code:
A
Abstract:
To provide a method for producing an organic crystal microparticle, whereby production and size adjustment of the particle can be readily carried out.
The method for producing the organic crystal microparticle comprises: dissolving an organic crystal in a good solvent having a boiling point lower than that of a poor solvent; and pouring the resulting organic crystal solution into the poor solvent, either intermittently in a plurality of batches or continuously in prescribed quantities, while removing the good solvent through evaporation, so as to precipitate the organic crystal particle of a nano-order size.
