FTIR analysis of raw saccharide starting materials and corresponding carbamate reaction products. a octyl isocyanate, b d-Mannose, c Mannose-C8 (MC8), d d-Xylose, e Xylose-C8 (XC8), f Viscose Xylan, g Viscose-C8 (VC8). The carbonyl peak corresponding to the carbamate bond appeared at 1725 cm−1, indicating a successful modification of mono- and oligosaccharides with the aliphatic side chains of octyl-isocyanate. The spectra of octyl isocyanate and raw materials are used as control samples to evaluate the functionalized materials
