Thermodynamics of binary mixtures containing oxaalkanes. Part 3. Monoethers, polyethers, acetals, orthoesters and cyclic monoethers + n-alkanes or cyclohexane

Thermodynamics of mixtures containing oxaalkanes. 5. Ether+benzene, or +toluene systems

“…As volume and surface units, the volume R CH 4 and surface Q CH 4 of methane are taken arbitrarily [21]. The geometrical parameters for the groups referred to in this work are given elsewhere [21][22][23]. (ii) The partition function is factorized into two terms, in such way that the excess functions are calculated as the sum of two contributions: a dispersive (DIS) term which represents the contribution from the dispersive forces; and a quasichemical (QUAC) term which arises from the anisotropy of the field forces created by the solution molecules.…”

Analysis of temperature dependence of some physical properties of (n-nonane+ tetraethylene glycol dimethyl ether)

“…A systematic investigation on these physical properties should cast light on molecular interactions. Moreover, properties of glymes and their mixtures have been widely studied by Kehiaian et al (1) who reported free Gibbs energies and excess molar enthalpies for the (alkane + glyme) systems. Excess molar volumes at T = 298.15 K were measured by Treszczanowicz et al (15) Other researchers determined that excess molar heat capacities for (alkane + glyme) mixtures show a W-shaped concentration dependence at several temperatures.…”

“…(1,2) The study of glymes has an important practical interest with a wide industrial application because of their use as absorbents in heat pump absorption technology. (3,4) In this work, we report the calculated values of isentropic compressibilities, excess molar volumes, changes of speeds of sound, changes of refractive indices and changes of isentropic compressibilities on mixing at the temperatures of (288.…”

Experimental and predicted excess molar enthalpies of binary mixtures containing 2,2′-oxybis[propane], benzene, butan-1-ol, 2-methylpropan-1-ol, 2-methyl-2-ene-1-propanol at 303.15K

“…The class of the systems containing monoether + alcohols was the subject of several works using model DISQUAC [18,[22][23][24][25].…”
