摘要
综述了近年来国内外学者们提出的新型纤维素溶剂体系,包括水相溶剂体系(氢氧化钠/水、碱/尿素/水和NaOH/硫脲/水、季铵盐/水和季鏻盐/水、熔融无机盐水合物)和有机溶剂体系(氯化锂/N,N-二甲基乙酰胺、离子液体、低共熔溶剂)溶解纤维素的能力及溶解机理,并探讨了不同溶剂体系的优缺点,为未来纤维素绿色溶剂开发利用提供参考。
The cellulose dissolution capability and dissolution mechanism of current novel solvent systems,including aqueous solvent systems(NaOH aqueous solution,alkali/urea and NaOH/thiourea aqueous solution,quaternary ammonium/phosphine aqueous solution,and molten inorganic salt hydrates)and organic solvent systems(LiCl/N,N-dimethylacetamide,ionic liquids and deep eutectic solvents)were reviewed.Sequentially,the advantages and disadvantages of various solvents were discussed,which could provided a reference for the future development and utilization of green cellulose solvents.
