Effect of temperature on the excess molar volumes of some alcohol+aromatic mixtures and modelling by cubic EOS mixing rules

Experimental triplet and quadruplet fluctuation densities and spatial distribution function integrals for liquid mixtures

“…58 The excess volume of mixing was taken from the 4-parameter RK coefficients provided by Šerbanović et al 61 The higher pressure derivatives of the excess volume of mixing were all approximated as zero as explained above.…”

Densities and Excess Molar Volumes of the Ternary Mixture 2-Butanol + Chloroform + Benzene and Binary Mixtures 2-Butanol + Chloroform, or + Benzene over the Temperature Range (288.15 to 313.15) K

“…[1][2][3][4][5] In this article, density F measurements of the ternary system of 2-butanol + chloroform + benzene and the 2-butanol + chloroform and 2-butanol + benzene binary constituents at temperatures (288. 15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric pressure are presented.…”

“…Optimization procedure for appropriate parameters or coefficients determination was performed using the methods described in our previous papers (Djordjević et al, 2007;Kijevčanin et al, 2007c;Šerbanović et al, 2006). Parameters of different CEOS and CEOS/G E mixing rules were treated as temperature independent or temperature dependent (only for whole temperature range correlation).…”

“…The dependence of E V on both composition and temperature, for the systems of alcohol and chlorobenzene, can be explained qualitatively as a balance between opposite effects (Letcher & Nevines, 1994;Saleh et al, 2005;Šerbanović et al, 2006): (i) positive contributions are predominantly attributed to hydrogen bond rupture and stretching of self-associated molecules of alcohol (in the alcohol lower region), (ii) negative contributions are considered to be a consequence of dipolar complexes involving alcohols and chlorobenzene (due to unlike intermolecular dipolar interactions), (iii) changes of free volume in real mixtures comprising alcohol monomers and multimers and chlorobenzene molecules and the geometrical fitting between components making this effect negative to V E . The magnitude and sign of V E are explained on the basis of some of above factors being predominant in certain mole fraction regions.…”
