摘要
Molecular interactions of the ternary mixtures of 1-butyl-3-methylimidazolium chloride ([C(4)C(1)im]Cl)-water-2,6-dimethoxyphenol (2,6-DMP, a phenolic monomer lignin model compound) were investigated in comparison with the [C(4)C(1)im] Cl-water binary systems through attenuated total reflection infrared spectroscopy. Results indicated that the microstructures of water and [C(4)C(1)im]Cl changed with varying mole fraction of [C(4)C(1)im]Cl (x(IL)) from 0.01 to 1.0. This change was mainly attributed to the interactions of [C(4)C(1)im]Cl-water and the self-aggregation of [C(4)C(1)im]Cl through hydrogen bonding. The band shifts of C-H on imidazolium ring and the functional groups in 2,6-DMP indicated that the occurrence of intermolecular interactions by different mechanisms (i.e., hydrogen bonding or pi-pi stacking) resulted in 2,6-DMP dissolution. In the case of x(IL)=0.12, the slightly hydrogen-bonded water was fully destroyed and [C(4)C(1)im]Cl existed in the form of hydrated ion pairs. Interestingly, the maximum 2,6-DMP solubility (238.5 g/100 g) was achieved in this case. The interactions and microstructures of [C(4)C(1)im]Cl-water mixtures influenced the dissolution behavior of 2,6-DMP.
