Ionically modified cellulose material, its preparation and its use |
摘要 |
Ionically modified cellulose material in which the ionic moiety is linked to the cellulose moiety via the carbonyl group of the bridge member -CO-NH-CH2-O- is suitable for being employed as the stationary phase in processes for separating mixtures of ionically charged components by chromatography, if the ionically modified cellulose material is obtainable from microcrystalline wood cellulose in the form of powder, as the starting material, the cellulose having a degree of polymerization of 490 to 550, and the cellulose powder consisting of particles having a specific BET surface area of 0.8 to 1.1 m2/g and a degree of swelling in water at 20 DEG C. of 4 to 6 ml/g.
