The use of size-exclusion chromatography in combination with multi-angle laser-light scattering analysis (SEC–MALLS) can provide useful information pertaining to the molecular mass parameters of wood celluloses and hemicelluloses. When wood holocelluloses containing significant amounts of hemicelluloses were soaked in ethylenediamine (EDA) and subjected to sequential EDA-removal and solvent-exchange...
Plant holocelluloses were prepared from softwood, gymnosperm, hardwood, and herbaceous species, and subjected to TEMPO-mediated oxidation using the TEMPO/NaBr/NaOCl and TEMPO/NaOCl/NaO2Cl systems in water at pH 10 and 6.8, respectively. Weight recovery ratios of the water-insoluble TEMPO-oxidized holocellulose (TOH) fractions and their carboxylate contents, sugar compositions, and X-ray diffraction...
