セルロース粒子の製造方法
Document Type and Number:
Japanese Patent JP7199763
Kind Code:
B2
Abstract:
The present invention provides: cellulose particles which are suppressed in acetic acid odor; and a method for producing cellulose particles, by which the above-described cellulose particles are able to be easily produced at low cost. Cellulose particles according to the present invention have an average particle diameter of from 1 to 300 μm, while having an acetic acid concentration of 0.5 ppm or less. In a method for producing cellulose particles according to the present invention, a cellulose acetate solution obtained by dissolving cellulose acetate into an organic solvent is suspended in water, thereby preparing a suspension liquid wherein cellulose acetate particles are dispersed in water; the organic solvent is removed from the suspension liquid; and the cellulose acetate particles are saponified so that the acetic acid concentration is 0.5 ppm or less, thereby obtaining cellulose particles.
