Abstract
The vapor-phase phosphorylation of cellulose by means of phosphorus trichloride (PCl3) and phosphorus oxychloride (POCl3) is presented. It was found that cellulose-O-dichlorophosphines (Cell-O6-PCl2) formed by the reaction of cellulose with PCl3 and cellulose-O-dichloro-oxyphosphines (Cell-O6-P(O)Cl2) formed by the reaction with P(O)Cl3 have been hydrolyzed to cellulose-O-hydrogenphosphates (P(III/V)) (Cell-O6-P(O)(H)-OH and (Cell-O6-P(O)(OH)2), respectively. Selected chemico-physical properties (SEM-EDS, 31P NMR, potentiometric titration) of both types of cellulose phosphates (Cell-O6-O-P(O)(H)-OH and Cell-O6-O-P(O)(OH)2) were compared.
