摘要：

Xylose crystal was obtained from cottonseed hull by the ethanol solventing-out crystallization process.The crystal was analyzed and determined by infrared spectrometer (IR),melting point tester,environmental scanning electron microscope (ESEM),high performance liquid chromatography (HPLC),and particle analyzer.The results showed that this xylose crystal is similar to that came from corncob in the IR spectroscopy and melting point,but their shape is different,the former likes long prism and the later is square.Under the optimized operation conditions,the purity of the crystal could be up to 99.64%(mass),and the yield 77.6%.The particle size at mediam is 151 μm with the variation 47%.These data indicate that ethanol solventing-out crystallization can be an industrial potential method for production of xylose.
