Preparation of Amide Derivatives of Oxidized Cellulose and Carboxymethylcellulose
Taubner, T. ; Synytsya, A. ; Sobek, Jiří ; Čopíková, J.
This work is focused on the preparation of amide derivatives of oxidized cellulose and carboxymethyl cellulose. Research involved the preparation of derivatives in two steps and the first preparation of a methyl ester of the starting polysaccharide, and then aminodealkyxilation with selected primary alkylamines, ethanolamine, ethylenediamine, hydrazine and hydroxylamine. Another part of the research included the direct amidation without intermediate steps starting polysaccharide preparation of methyl ester using the same reagents and support of microwave radiation. The obtained products were monitored by FT-IR spectroscopy and organic elemental analysis.
