Process for preparing porous cellulose spherical particles |
| abstract |
A solution of cellulose triacetate in a mixed solvent consisting essentially of a chlorinated hydrocarbon with a boiling point lower than that of an aqueous medium and an aliphatic higher alcohol with 6 or more than 6 carbon atoms is suspended into the aqueous medium to form droplets of the above-mentioned solution, and then the chlorinated hydrocarbon in the droplets is removed by evaporation to obtain spherical particles of cellulose triacetate containing the aliphatic higher alcohol. The spherical particles thus obtained are saponified and removed of the aliphatic higher alcohol, to prepare porous cellulose spherical particles. |
