Measurements of activity coefficients at infinite dilution of organic solutes and water on polar imidazolium-based ionic liquids
The activity coefficients at infinite dilution, c13, of 55 organic solutes and water in three ionic liquids with the common cation 1-butyl-3-methylimidazolium and the polar anions Cl , [CH3SO3] and [(CH3)2PO4] , were determined by (gas + liquid) chromatography at four temperatures in the range (358.15 to 388.15) K for alcohols and water, and T = (398.15 to 428.15) K for the other organic solute...
متن کاملModeling the Solubility of Acid Gases in Ionic Liquids
In this work, the PC-SAFT equation of state (EoS) has been used to model the solubility of acid gases (CO2 and H2S) in two imidazolium-based ionic liquids (ILs) ([C8-mim][PF6] and [C8-mim][Tf2N]). Parameters of pure ILs were estimated using experimental densities. Two strategies were considered to model densities of pure ILs. In strategy 1, ILs were modeled as nonassociating compounds and in st...
متن کاملThe Solubility of Gases in Ionic Liquids
In this Perspective, we provide a detailed discussion of the techniques and methods used for determining the solubility of gases in ionic liquids (ILs). This includes various experimental measurement techniques, equation of state (EOS) modeling, and predictive molecular-based modeling. Many of the key papers from the past 15 years are discussed and put into the context of the latest advances in...
متن کاملPartition Coefficients of Organic Compounds in New Imidazolium and Tetralkylammonium Based Ionic Liquids Using Inverse Gas Chromatography
Partition coefficients of 51 organic compounds in two ionic liquids (IL), 1-ethyl-3-methylimidazolium dicyanamide and trimethylhexylammonium bis((trifluoromethyl)sulfonyl)amide, were measured using inverse gas chromatography from (322.5 to 352.5) K. These partition coefficients were converted into water-to-IL partition coefficients using the corresponding gas-to-water partition coefficients. Bo...
متن کاملOstwald solubility coefficients of some industrially important substances.
Solubility coefficients in blood for benzene, toluene, and xylene were determined as 6.5, 16, and 42 respectively. In lard and olive oil, which were taken to represent human fat, corresponding values were about 450, 1300, and 3900. The coefficient for vinyl chloride in lard and olive oil was 20; the value in blood was too low to be determined by the technique used. Trichloroethylene, used as a ...
