In this study, the hemicelluloses
were isolated from small-flowered tamarisk (Tamarix parviflora) which might
be useful raw material in the industrial area, then esterified using octanoyl,
decanoyl and lauroyl chloride. Afterwards, obtained hemicellulose esters were
characterized. Monosaccharide composition of small-flowered tamarisk wood and hemicelluloses were determined by
HPLC. The substitution degrees of esters were found between 0.68 and 0.81 and yield percentages between 54.13 and 58.23. The values of bands at 3410, 2922, 2854 and 1742 cm-1 in
FTIR spectra of esters showed that the derivation of hemicelluloses occurred.
Esters presented lower thermal stability compared to natural hemicelluloses
after thermogravimetric analysis. The characteristic properties of produced hemicellulose
esters indicated that these esters were found to be at a sufficient level for
raw material in the production of biodegradable and environmentally degradable
plastics, resins and films.
