摘要：
The use of ultrafiltration to fractionate dextran solutions in order to obtain fractions for the synthesis of dextran derivatives was investigated. Several experiments were carried out in two available commercial ultrafilters. The operation was evaluated by the recovery yield and process time. Dextran solutions can be fractionated being concentrated up to 9 fold in a PM30, but no more than double in a PM5 hollow fibre membrane cartridge.
