METHOD FOR CONTINUOUS PROCESSING DERIVATIVES OF POLYSACCHARIDES Russian patent published in 2008 - IPC C08B11/12 C08B30/00 

FIELD: chemical technology, polymers.

SUBSTANCE: invention proposes a method for continuous processing derivatives of polysaccharides as a solid substance that involves reaction and/or conditioning in suspension with liquid reactive components by the following steps: (a) preliminary temperature-controlled suspending flow consisting of a solid substance SE and liquid phase LE is added into upper part of column continuously wherein this column is filled almost completely with temperature-controlled similar or other liquid phase L after this process; (b) solid substance SE is converted to solid substance SA by gravitation and reaction of and/or conditioning with liquid phase L and precipitated freely through liquid phase in bottom part of column; (c) if necessary, gases G evolved from column are removed from upper part of column, and (d) solid substance SA is removed from the process continuously through bottom part of column as a suspension flow at constant level of the column filling by addition of liquid phase LR removed early from upper part of column and transporting as a separating compound to bottom part of column and/or by addition of novel liquid phase LN into bottom part of column.

EFFECT: improved processing method.
