Abstract
The extraction properties of choline dicyanamide, namely the selectivities and capacities for heptane/benzene, heptane/thiophene, heptane/pyridine, and heptane/1-nitropropane separation problems, were determined and compared to the literature values for other ionic liquids based on dicyanamide anion. The extraction parameters were calculated from activity coefficients at infinite dilution determined by gas–liquid chromatography at the temperatures (298.15 – 368.15) K. The density of the investigated ionic liquid was also measured at this temperature range. Additionally, to better understand the interactions between the ionic liquid and different groups of solvents, activity coefficients at infinite dilution were determined for various solutes: alkanes, cycloalkanes, alkenes, alkynes, aromatic hydrocarbons, alcohols, ethers, ketones, esters, butanal, thiophene, nitrogen compounds and water in the ionic liquid choline dicyanamide at this temperature range.
期刊介绍：
The Journal of Chemical Thermodynamics exists primarily for dissemination of significant new knowledge in experimental equilibrium thermodynamics and transport properties of chemical systems. The defining attributes of The Journal are the quality and relevance of the papers published.
The Journal publishes work relating to gases, liquids, solids, polymers, mixtures, solutions and interfaces. Studies on systems with variability, such as biological or bio-based materials, gas hydrates, among others, will also be considered provided these are well characterized and reproducible where possible. Experimental methods should be described in sufficient detail to allow critical assessment of the accuracy claimed.
Authors are encouraged to provide physical or chemical interpretations of the results. Articles can contain modelling sections providing representations of data or molecular insights into the properties or transformations studied. Theoretical papers on chemical thermodynamics using molecular theory or modelling are also considered.
The Journal welcomes review articles in the field of chemical thermodynamics but prospective authors should first consult one of the Editors concerning the suitability of the proposed review.
Contributions of a routine nature or reporting on uncharacterised materials are not accepted.
