Kind Code:
A1
Abstract:
According to one embodiment, a method for producing porous cellulose particles is provided. The method comprises: (a) dissolving cellulose diacetate in a solvent to prepare a cellulose diacetate solution, (b) dispersing the cellulose diacetate solution in a medium that is immiscible with the cellulose diacetate solution to produce a dispersion system, (c) cooling the dispersion system, (d) adding a poor solvent to the cooled dispersion system to cause cellulose diacetate particles to precipitate, and (e) saponifying the cellulose diacetate particles.
