Abstract:
Provided is a novel method for producing cellulose beads, the method being capable of suitably producing spherical cellulose beads. The method for producing cellulose beads includes: (Step 1) preparing a coagulating bath having a first liquid medium phase and a second liquid medium phase; (Step 2) forming a particulate cellulose solution in the first liquid medium phase by supplying a cellulose solution to the first liquid medium phase of the coagulating bath; and (Step 3) coagulating the particulate cellulose solution by supplying the particulate cellulose solution in the first liquid medium phase to the second liquid medium phase.
