Activity Coefficients at Infinite Dilution of Organic Solutes in the Ionic Liquid 1-Ethyl-3-methyl-imidazolium Nitrate

Popis výsledku v původním jazyce

Infinite dilution activity coefficients and gas-liquid partition coefficients of 30 selected hydrocarbons, alcohols, ketones, ethers, esters, haloalkanes, nitrogen- and sulphur-containing compounds in the ionic liquid (IL) 1-ethyl-3-methylimidazolium nitrate [EMIM][NO3] were determined by gas-liquid chromatography at five temperatures in the range from (318.15 to 353.15) K. Relative contribution of adsorption at gas-liquid interphase to the overall solute retention, as examined by varying sample size and IL loading in the column, was found negligible. Partial molar excess enthalpies and entropies at infinite dilution were derived from the temperature dependence of the limiting activity coefficient values. The Linear Free Energy Relationship (LFER) solvation model was used to correlate successfully the gas?liquid partition coefficient values. The LFER correlation parameters and excess thermodynamic functions were analyzed to disclose molecular interactions operating between the IL and t
