Thermodynamics of mixtures of hexane and heptane isomers with normal and branched hexadecane

Thermodynamic and acoustic properties of (heptane+dodecane) mixtures under elevated pressures

“…Depolarised Rayleigh scattering and H E measurements showed that the correlations of orientations between neighbouring molecules in the pure hexadecane were replaced by weaker correlations between nonane and hexadecane in the mixture [51]. Barbe and Patterson [51] proved that longer alkanes (from hexane to octane) cause a smaller destruction of order in hexadecane; the longer chain results in easier correlation with hexadecane. However, the order contribution to the equimolar H E and TS E is not negligible in all the systems mentioned above.…”

Excess molar volumes and dynamic viscosities for binary mixtures of toluene+n-alkanes (C5–C10) at T=298.15K – Comparison with Prigogine–Flory–Patterson theory

“…The parameters was computed using the group contribution method of Barbe and Patterson [6]. w is a composition variable given by…”

“…We have also performed a theoretical study under the frame work of the Prigogine-Flory-Patterson (PFP) [6][7][8][9][10][11][12]. This theory born as a modification of mixtures.…”

Excess molar volumes of binary mixtures with 2-pentanone and 1-chloroalkanes at 298.15 and 308.15 K

“…To enlarge the data base needed to calculate the interaction parameters we report in the present paper the experimental excess molar volumes at 298.15 and 308.15 K of 2-pentanone ' T o whom correspondence should be addressed. The version of the Flory model (8, 9) due to Patterson and co-workers (10)(11)(12), named the Prigogine-Flory-Patterson (PFP) model, has been used often recently to correlate and to predict such thermodynamic properties of organic mixtures as hE, vE, c;. The PFP model is very useful to analyze the influence of the size, shape, and momentum of the molecules on the behaviour of binary mixtures.…”
