Heating up: Improved recyclability is necessary for ionic liquids destined for wood‐based bioprocessing platforms. New “distillable” molten acid–base conjugates efficiently dissolve cellulose at temperatures of 100 °C. Increased temperature induces a shift of the acid–base equilibrium toward the neutral species (see picture, TMG=1,1,3,3‐tetramethylguanidine), thus affording a vapor pressure and allowing
升温:对于用于木质生物处理平台的离子液体,必须提高可回收性。新的“可蒸馏的”熔融酸碱共轭物可在100°C的温度下有效溶解纤维素。温度升高引起酸碱平衡向中性物质转移(见图,TMG = 1,1,3,3-四甲基胍),从而提供蒸气压并允许蒸馏混合物。
