| Abstract: | Cellulose microspheres were prepared using the cellulose-ionic liquid(IL) solution was prepared by directly dissolving by reversed-phase suspension technique.Effects of the used cellulose type,cellulose content in the solution,disperse phase,agitation speed,temperature on particle size distribution were discussed.In the case of 2% cotton cellulose/IL solution,heat transfer oil as disperse phase,50:1 of volume ratio of oil and solution,PEG 600 as disperse agent,500 r/min of the agitation speed and 80 ℃,55% cellulose microspheres with particle size 0.45 to 0.20 mm can be obtained. |
