半纤维素在离子液体中的溶解和再生过程研究
Research on the dissolution and regeneration of hemicellulose in ionic liquids
摘要
Abstract
Six typical imidazolium-based ionic liquids were prepared and used as green solvents in the dissolu-tion of the model compound of hemicellulose xylan.The result showed that chloride salts had higher dissolving capacity of xylan.The solubility of xylan could be as high as 12.09 g at 373.2 K.When containing the same anions,the ionic liquids with hydroxyethyl groups had highest dissolving capacity,followed by the ones with allyl and butyl groups.Based on IR spectra measurements,the composition and structure change before and after regeneration of xylan were studied.It was confirmed from microcosmic angle that the hydrogen bonding network in xylan had been partly destroyed by ionic liquids.This process was the main reason why xylan could be dissolved in ionic liquids.关键词
