Abstract
A method of manufacturing cellulose microspheres is proposed which is high in productivity, and takes into consideration the safety and environmental aspects. The cellulose microspheres are manufactured by mixing at least three parts by weight of a water-soluble polysaccharide with an alkaline cellulose solution containing one part by weight of cellulose to prepare a minute dispersion in which are formed minute droplets made of cellulose-rich phase, and coagulating and regenerating the minute droplets.
Claims4
A method of manufacturing cellulose microspheres having a particle size of 1-100 μm, said method comprising mixing an alkaline cellulose solution with a water-soluble polysaccharide which remains water-soluble in an acid, so that the mixture will contain at least three parts by weight of the water-soluble polysaccharide to one part by weight of cellulose content in the alkaline cellulose solution, to prepare a minute dispersion in which are formed minute droplets made of cellulose-rich phase and bringing the minute dispersion into contact with an acid to coagulate and regenerate said minute droplets.
