Osmotic coefficients of alcoholic mixtures containing BMpyrDCA: Experimental de...
N. Calvar; Á. Domínguez; E. A. MacedoThe vapour pressure osmometry technique (VPO) has been used to obtain the osmotic coefficients of the binary mixtures of the primary and secondary alcohols 1-propanol, 2-propanol, 1-butanol, 2-butanol and 1-pentanol with the ionic liquid 1-butyl-1-methylpyrrolidinium dicyanamide, BMpyrDCA. From these coefficients, the corresponding activity coefficients and vapour pressures of the mixtures have been also determ...

N. Calvar; Á. Domínguez; Eugénia A. MacedoThe osmotic and activity coefficients and vapour pressures of mixtures containing primary (1-propanol, 1-butanol and 1-pentanol) and secondary (2-propanol and 2-butanol) alcohols with pyrrolidinium-based ionic liquids (1-butyl-1-methyl pyrrolidinium bis(trifluoromethylsulfonyl)imide, C(4)MpyrNTf(2), and 1-butyl-1-methyl pyrrolidinium trifluoromethanesulfonate, C(4)MpyrTFO) have been experimentally determined at...

N. Calvar; E. J. González; A. Domínguez; E. A. MacedoThe osmotic and activity coefficients and vapor pressures of binary mixtures containing the alcohol 1-propanol and the ionic liquids 1-ethyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide, C2MpyNTf2, 1-propyl-3- methylpyridinium bis(trifluoromethylsulfonyl)imide, C3MpyNTf2, 1-butyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide, C4MpyNTf2 and 1-butyl-3-methylpyrrolidinium bis(trifluoromethylsulfonyl...

Eugénia A. Macedo; N. Calvar; E. J. González; A. DomínguezThe osmotic (f) and activity coefficients and vapor pressures of binary systems containing the primary alcohol 1-propanol and 1-alkyl-3-methylpyridinium ionic liquids, CnMpy+ with n = 2, 3, 4, and the IL 1,1-butylmethylpyridinium, C4Mpyr+,all of them with the anion bis(trifluoromethylsulfonyl)imide, NTf2 -, were determined at 323.15 K using the vapor pressure osmometry technique. The f and vapor pressure depres...
Physical and excess properties for binary systems containing an alcohol and ion...
Eugénia A. Macedo; E. J. González; N. Calvar; P. Fernández; A. DomínguezThe density, speed of sound, and refractive index for binary systems containing ethanol, or 1-propanol, or 2-propanol mixed with the ionic liquids 1-butyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide or 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide were measured at 298.15 K and 1 atm. From the experimental data, excess molar volumes (VE), excess molar isentropic compressibility (KS,m/E...

E. J. González; N. Calvar; P. Fernández; A. Domínguez; E. A. MacedoIn this paper, density, speed of sound and refractive index of six binary systems (alcohol + ionic liquid) were measured, along the whole composition range, at T = 298.15 K and atmospheric pressure. The ionic liquids used in this work are constituted by different cations (pyridinium and pyrrolidinium), anions (trifluoromethanesulfonate and dicyanamide) and alkyl-side chain (propyl- and butyl-). From the experim...
