摘要: The density and viscosity data of three binary liquid mixtures containing the ionic (IL) 1-ethyl-3-methylimidazolium tetrafluoroborate organic solvents, dimethylacetamide (DMAC), dimethylformamide (DMF), dimethyl sulfoxide (DMSO) were obtained under atmospheric pressure, at temperatures 303.15 to 333.15 K over entire composition range. A vibrating-tube digital meter a capillary viscometer used for measurements, respectively. Excess molar volumes (VE) deviations (Δη) mixture system calculated from experimental satisfactorily fitted with Redlich–Kister equation. Adding DMAC, DMF, DMSO led negative values VE Δη. This finding revealed that packing constituents was more efficient, anion–cation interaction IL decreased in mixtures. sequences Δη this study are also discussed using interm...
