Abstract

For the temperature range (80 to 120) °C, viscosity data are reported for imidazolium-based ionic liquids 1-octyl-3-methylimidazolium chloride [Omim][Cl], 1-hexyl-3-methylimidazolium chloride [Hmim][Cl], 1-butyl-3-methylimidazolium chloride [Bmim][Cl], 1-ethyl-3-methylimidazolium chloride [Emim][Cl], 1-ethyl-3-methylimidazolium acetate [Emim][Ac], 1-butyl-3-methylimidazolium acetate [Bmim][Ac], and 1-butyl-3-methylimidazolium dicyanamide [Bmim] [N(CN)₂]. Acetate-based ionic liquids have considerably lower viscosities than the corresponding chloride-based ILs. At 25 °C, viscosity data are reported for binary mixtures of [Bmim][Ac] with diluents water, acetonitrile, dimethylformamide (DMF), and ethylene glycol. Even a small concentration of diluent very much reduces the viscosity of an ionic liquid.
