Volumetric properties of binary mixtures of tributylamine with benzene derivatives and comparison with ERAS model results at temperatures from (293.15 to 333.15)K

Density and Speed of Sound of Binary Mixtures of Ionic Liquid 1-Ethyl-3-methylimidazolium Tetrafluoroborate,N,N-Dimethylformamide, andN,N-Dimethylacetamide at Temperature Range of 293.15–343.15 K: Measurement and PC-SAFT Modeling

“…The calculated excess molar volumes of the binary mixtures were correlated by the temperature-dependent Redlich–Kister equation where x i and x j are the mole fractions of the components i and j , respectively, A pq is the temperature-independent parameter of the binary mixtures, and T is the absolute temperature. These parameters were obtained by the unweighted least-squares method . The adjustable parameters, A pq , for all the binary mixtures were tabulated in Table together with the standard deviation, σ, calculated using the following relation where k is the number of adjustable parameters, A pq , and n is the number of experimental data.…”

Thermodynamic characterization of binary mixtures of poly(propylene glycol) 425 with toluene and o-, m- and p-xylenes

“…However, to the best of our knowledge this should not affect the calculated deviations in viscosity or in refractive indices of these compounds, since the impact of water cancels in the calculations.

Volumetric and FT-IR Studies of the Binary Liquid Mixtures of Tributylamine and Alkyl Ester (C1–C5)

“…The positive values of V m E are due to physical effects, which consist of dispersal forces and weak physical interactions. The V m E values for these systems indicate the disassociation of the mixing components, resulting in volume expansion. − The change in ideal behavior can be interpreted on the basis of polarity and chain length. When an ester is added to TBA, it is predicted that bonding and electrostatic interactions already existing between the pure components break, resulting in positive contributions to the volumes of the mixtures.…”
