Imidazolium-based ionic liquids (ILs) are widely studied in the biochemical process. In this work, because of the high viscosity of the IL, namely, 1-butyl-3-methylimidazolium acetate, the organic solvents of dimethyl sulfoxide, N,N-dimethylacetamide, and N,N-dimethylformamide were selected as the additives or diluents to reduce the viscosity of IL. The experimental measurements of the viscosity and density were performed at atmospheric pressure in the temperature ranging from (303.15 to 348.15) K. The influences of the organic solvents on the properties of IL were quantitatively analyzed. The excess properties were calculated to further understand the interaction between the IL and organic solvents.

有机溶剂对乙酸1-丁-3-甲基咪唑鎓盐性能的影响

基于咪唑鎓的离子液体（ILs）在生化过程中得到了广泛的研究。在这项工作中，由于IL的高粘度，即乙酸1-丁基-3-甲基咪唑鎓，选择了二甲基亚砜，N，N-二甲基乙酰胺和N，N-二甲基甲酰胺的有机溶剂作为添加剂或稀释剂。降低IL的粘度。在大气压下于（303.15至348.15）K的温度下进行粘度和密度的实验测量。定量分析了有机溶剂对IL性能的影响。计算出多余的特性以进一步了解IL和有机溶剂之间的相互作用。
