aserrín, celulosa, extracción, cristalinidad, difracción de rayos XAbstract
Cellulosic components were extracted from wood residues obtained from fumiture fabrication. The residues were previously treated with Soxhlet extraction to obtain oils and toluene-soluble compounds. The residue obtained after toluene extraction was treated using a modified Kurschner-Hoiffer method, refluxing with a mixture containing methanol, nitric acid, sodium hydroxide and hypochlorite. The residues obtained from each extraction were analyzed with infrared spectroscopy, differential scanning calorimetry. While X-ray diffraction was used in order to determine the cellulose degree of crystallinity.
