Abstract: A process is described for the continuous preparation and/or workup of polysaccharide derivatives by reaction and/or conditioning in a suspension with liquid reaction partners, in which, in accordance with FIG. 1, a) a preferably pumpable suspension stream of solids SE and liquid phase LE, if appropriate preheated to 185° C., is continuously introduced into the top region of a column, if appropriate under a pressure buffer of up to 6×106 Pa, which is virtually filled with the same liquid phase L, or another process-specific liquid phase L of preferably the same temperature, then b) the solids SE sediments freely due to the action of gravity through the liquid phase L to the column bottom, the solids SE converting to the solids SA by reaction and/or conditioning with the liquid phase L and c) possibly ascending gases G are discharged from the column via the column top and d) the solids SA is again continuously discharged as a suspension stream at the column bottom continuously by adding liquid phase LR taken off at the column top at a constant column filling level and transported in a separate connection, or liquid phase LN newly added from the outside to the column bottom.

Abstract: The present invention relates to a process for the manufacture of cellulose ethers. The process involves: (a) providing a perforated disk having a plurality of perforations; and (b) forcing feed cellulose ether through at least some of the perforations of the perforated disk, thereby forming compressed cellulose ether. The compressed cellulose ether formed in accordance with the method of the present invention has a higher bulk density and a more uniform particle size distribution than known cellulose ethers prepared by other processes.
