SYNTHESIS AND CHARACTERIZATION OF CHITOSAN ALKYL PHOSPHATE

Chitosan is a natural polysaccharide constituted by D-glucosamine units beta-(1 4) linked. In the present work new phosphorylated derivatives of chitosan were synthesized. The heterogeneous reaction was carried out using diethyl chlorophosphate as phosphorylating agent. The relation of the degree of...
