A new approach to preparation of granulated materials based on chitosan and its imidazole derivative

Аннотация

A new approach to preparation of granulated materials based on chitosan and N-(5-methyl-4-imidazolyl)- methyl chitosan was developed. The procedure is simple and efficient and involves the use of glutaraldehyde as cross-linking agent without using precipitants. The composition and structural features of the materials obtained were determined by elemental analysis and Fourier IR spectroscopy. The dependence of the degree of material swelling on the degree of functionalization with glutaraldehyde was determined. The polymer granules were used as support for Pd0-containing catalysts for reduction of organic compounds.
