One organic and three alkaline hemicellulosic fractions were isolated by an ultrasound-assisted extraction which partially delignified the fast-growing poplar wood. Successive treatments were conducted with dimethyl sulfoxide under ultrasonic irradiation at 570W, 25 degrees C for 30min, 70% ethanol containing 1% NaOH, 3% NaOH and 6% NaOH at 75 degrees C for 3h, respectively. The four hemicellulosic fractions obtained were comparatively studied by sugar analysis, alkaline nitrobenzene oxidation… CONTINUE READING
