    Microwave-assisted modification of polysaccharides is a relatively new method. Microwave heating is used for improving of extraction, hydrolytic and synthetic procedures. Modification of polysaccharides with the microwave irradiation is effective, fast and economic. The aim of this study was to apply the microwave irradiation in synthesis of carboxymethylcellulose (CMC) derivatives. This polysaccharide and its methyl ester reacted with n-butylamine yielding N-butylamide. The reactions were subsequently monitored by FUR and organic elemental analysis of the products. Degree of substitution (DS) and reaction yields were calculated based on nitrogen and carbon contents. The optimal reaction conditions were found to prepare product with the highest DS. Amino-de-alkoxylation of CMC methyl ester was significantly more effective than direct microwave assisted amidation of CMC, and microwave assisted significantly improved amino-de-alkoxylation.
