Process for recovering cellulose ether from an aqueous medium containing cellulose ether (Process for recovering cellulose ether from an aqueous medium containing such cellulose ethers)

摘要

Comprising flowing a slurry to a hydrocyclone in the manner that they are produced under conditions that a particular cellulose ether solid in the slurry is produced at a temperature above the gelation point of the cellulose ether ether solids in the slurry, Aqueous slurry, or a method of recovering a demanded cellulose ether solid in an aqueous slurry discharged from a centrifuge or a filter from which a part of the cellulose ether solid is removed from the reactor.
