ABSTRACT
Density, surface tension, dynamic viscosity, and electrical conductivity of a new air and water stable hydrophobic amide-based task-specific ionic liquid (IL) 1-butylamide-3-ethylimimdazolium bis(trifluoromethylsulfonyl)imide ([EimCH2CONHBu][NTf2]) were determined in the temperature range of T = (283 to 363) K. The volumetric and surface properties were discussed using the density and surface tension values. The thermal expansion coefficient was predicted by the interstice model theory. The decomposition temperature was determined with the thermogravimatric analysis (TG). The molar conductivity data were calculated by density and electrical conductivity values. Temperature dependence on dynamic viscosity and electrical conductivity values of the [EimCH2CONHBu][NTf2] were fitted by the VFT equation. The Arrhenius equation was also used to fit the dynamic viscosity and electrical conductivity values.
