Physical properties of (propyl Propanoate + hexane + toluene) at 298.15 K
The Journal of Chemical Thermodynamics, 2007Co-Authors: Sonia Freire, Oscar Cabeza, Luisa Segade, Eulogio JiménezAbstract:Abstract The aim of this paper is to report experimental densities, excess molar enthalpies and refractive indexes of the ternary system (propyl Propanoate + hexane + toluene) and of the corresponding binary mixtures (propyl Propanoate + toluene) and (hexane + toluene) at the temperature 298.15 K and atmospheric pressure, over the whole composition range. Also, the excess molar volumes and the changes in the refractive index on mixing have been calculated from the measured data for all mixtures.

Experimental and theoretical surface tension deviations in the binary systems propyl Propanoate + o-, m- and p-xylene at 298.15 K
Fluid Phase Equilibria, 2005Co-Authors: Montserrat Domínguez-pérez, Luisa Segade, C. Franjo, Oscar Cabeza, Eulogio JiménezAbstract:Abstract This paper reports on the surface tension of the binary mixtures {propyl Propanoate + o-xylene}, {propyl Propanoate + m-xylene} and {propyl Propanoate + p-xylene} at the temperature 298.15 K and atmospheric pressure, over the whole composition range. The surface tension deviations obtained were correlated with a Redlich–Kister type equation. These data were compared with five different theoretical approaches. Among them we apply the theories of Hildebrand and Scott for ideal solutions and their extension of Guggenheim's ideal solution equation, valid for systems containing molecules of significantly different size; the Brock and Bird theory, based only in the critical values of the pure compounds; the Sudgen's equation based in the parachor, which needs the knowledge of density for the whole composition in the mixture; and finally, the Prigogine's refined theory, which takes into account the critical values and the temperature dependence of surface tension. We will discuss results from those five theoretical models applied to the experimental data presented in this work, and also to other previously published data. Also, we will discuss the influence of the surface molar area parameter value on the models that need it.

Excess molar volumes and enthalpies for the binary systems propyl Propanoate + o-xylene, m-xylene, and p-xylene at 298.15 K
Thermochimica Acta, 2004Co-Authors: Montserrat Domínguez-pérez, C. Franjo, Luisa Segade, Julieta Jiménez De Llano, Oscar Cabeza, Eulogio JiménezAbstract:This paper reports excess molar enthalpies, H E m , and excess molar volumes, V E m , of the binary systems {propyl Propanoate + o-xylene}, {propyl Propanoate + m-xylene} and {propyl Propanoate + p-xylene} at the temperature 298.15 K and atmospheric pressure, over the whole composition range. V E m was calculated from the experimental measurement of the corresponding densities, while H E m was measured directly. The excess magnitudes were correlated to a Redlich-Kister type equation. Finally, we will discuss the results of the three mixtures studied here and by comparison with other binary systems containing propyl Propanoate and a benzene-based compound previously published.

Densities, surface tensions and refractive indexes for propyl Propanoate + hexane + ethylbenzene at 298.15 K
Fluid Phase Equilibria, 2003Co-Authors: Montserrat Domínguez-pérez, Luisa Segade, Julieta Jiménez De Llano, Oscar Cabeza, Sonia Freire, Esther Rilo, Eulogio JiménezAbstract:Abstract This paper reports experimental densities, surface tensions and refractive indexes of the ternary system (propyl Propanoate+hexane+ethylbenzene) and of the corresponding binary mixtures (propyl Propanoate+ethylbenzene) and (hexane+ethylbenzene) at the temperature 298.15 K and atmospheric pressure, over the whole composition range. Also, the excess molar volumes, surface tension deviations and changes in the refractive index on mixing have been calculated. The experimental values were compared with the results obtained by the empirical expressions Jacob and Fitzner, Kohler, Colinet, Knobeloch–Schwartz, Tsao and Smith, Toop, Scatchard et al., Hillert, and Mathieson–Tynne for estimating excess ternary properties from binary data.

Journal of Thermal Analysis and Calorimetry, 2002Co-Authors: Sonia Freire, Luisa Segade, Sandra García-garabal, J. Jiménez De Llano, M. Dominguez, Eulogio JiménezAbstract:Excess molar enthalpies for the ternary mixture {propyl Propanoate + hexane + chlorobenzene} and the binary mixtures {propyl Propanoate + chlorobenzene} and {hexane + chlorobenzene} were determined at the temperature 298.15 K and normal atmospheric pressure. The experimental values were measured using a Calvet microcalorimeter. Excess molar enthalpies obtained were also used to test empirical expressions for estimating ternary properties from binary results.

Journal of Chemical & Engineering Data, 1997Co-Authors: Eulogio Jiménez, C. Franjo, Luisa Segade, And José Luis Legido, M. I. Paz AndradeAbstract:Excess molar volumes at the temperature 298.15 K were measured for the ternary systems (x1ethyl Propanoate + x2hexane + (1 − x1 − x2)heptan-1-ol or (1 − x1 − x2)octan-1-ol} and for binary mixtures {x1ethyl Propanoate + (1 − x1)n-hexane}, {x1ethyl Propanoate + (1 − x1)heptan-1-ol}, {x1n-hexane + (1 − x1)heptan-1-ol}, {x1ethyl Propanoate + (1 − x1)octan-1-ol}, and {x1n-hexane + (1 − x1)octan-1-ol}. Excess molar volumes were determined using a densimeter Anton Paar DMA 60/602. The experimental values were compared with the results obtained with some empirical methods for the estimation of ternary properties from binary results.
