Process for preparing porous cellulose spherical particles |
| abstract |
A solution of cellulose triacetate in a mixed solvent comprising a chlorinated hydrocarbon with a boiling point lower than that of an aqueous medium and an aliphatic higher alcohol with 6 or more carbon atoms is suspended as droplets in the aqueous medium, and then the chlorinated hydrocarbon in the droplets is removed by ecapora- tion to obtain spherical particles of cellulose triacetate containing the aliphatic higher alcohol. The spherical particles thus obtained are saponified and remaining aliphatic higher alcohol is removed, thereby giving porous cellulose spherical particles. |
