The electrical conductivity of dilute solutions of the ionic liquids 1-ethyl-3-methylimidazolium tetrafluoroborate [emim][BF4] and 1-butyl-3-methylimidazolium tetrafluoroborate [bmim][BF4] in N,N-dimethylacetamide (DMA) have been measured over the temperature range from (283.15 to 318.15) K. The conductance data was analyzed using the low concentration Chemical Model (lcCM) in terms of the ionic association constant, K A, the limiting molar conductivities, Λo, and distance parameters, R. Slight ionic association was found for the ionic liquids in DMA within the investigated temperature range. From the temperature dependence of the limiting molar conductivities the Eyring activation enthalpy of charge transport was designated. The thermodynamic parameters such as Gibbs free energy, entropy, and enthalpy for the process of ion pair formation were estimated from the ion association constants at various temperatures. The obtained results were compared with those in N,N-dimethylformamide.

“…The excess volumes of DMF in mixtures with water [4,6], substituted benzenes [7], aniline and benzonitrile [8], benzyl alcohol and acetophenone [9], ethane-1,2-diol [10], 1-alkanols [11], ethanol [12], propylene carbonate [13], 2-propoxyethanol, and 2-iso-propoxyethanol [14], or ketones [15] have been already reported in the literature. However, no effort appears to have been made to collect the densities and the excess volumes for the mixtures of N,Ndimethylformamide with diethers and there is no evidence for specific interactions between DMF with diethers.…”

Densities, ρ, and ultrasonic speeds, u of mixtures of 1-butanol or iso-butanol or t-butanol with equimolar mixture of (N,N-dimethylacetamide + Ethyl acrylate) over the entire composition range have been measured at T=308.15 K. Using the experimental results, deviation in ultrasonic speed, Δu, deviation in isentropic compressibility, Δks, excess molar volume, VmE, excess intermolecular free length, LfE, and excess acoustic impedance, ZE, have been calculated. The variation of these properties with composition of the mixtures has been discussed in terms of molecular interactions in these mixtures. The deviation/excess properties have been fitted to Redlich-Kister type polynomial and the corresponding standard deviations have been calculated. Negative values of VmE, Δks, and LfE and positive values of Δu, and ZE are observed over the entire composition range. The observed negative and positive values of deviation/excess properties are attributed to the strong interactions between the unlike molecules of the mixtures. Further theoretical values of sound velocity in the mixtures have been evaluated using various theories and compared with experimental sound velocities to verify the applicability of such theories to the systems studied. Theoretical ultrasonic velocity data has been used to study molecular interactions in the systems investigated.
