Hemicelluloses were isolated from hybrid poplar with the single-step alkaline extraction. Neutralization and subsequent ethanol precipitation were used to recover them. Their structures were investigated using sugar analysis, Fourier transform infrared and (13)C nuclear magnetic resonance spectroscopy. The hemicelluloses were characterized by particle size analyzer, gel permeation chromatography and thermogravimetric analyzer. 36.4% and 50.4% of the original hemicelluloses were isolated in the… CONTINUE READING
