摘要: The experimental data of viscosity and density for six binary mixtures water (methanol or ethanol) with an ionic liquid, 1-butyl-3-methylimidazolium dimethylphosphate ([BMIM][DMP]) 1-ethyl-3-methylimidazolium ([EMIM][DMP]), were measured in the temperature range (293.15 to 333.15) K at atmospheric pressure using a viscometer densimeter. solution behavior is discussed terms variation excess volume temperatures compositions. It found that both studied show negative deviation from ideal behavior, decreases drastically increase mole fractions solvents. quite low, (1.0 1.9) cm3·mol–1; moreover, it shows monotonic decrease increasing aqueous ILs reverse trend IL solutions ...
