“…At a particular temperature, ∆η varied in the order: THF + NBL > THF + NPL. Similar results of negative ∆η in THF + NPL system at 303.15 K were observed previously by Gupta et al [5]. Also, same types of trend are found for THF + MNL (Methanol) by [7].…”

“…Previously, Gupta et al [5] and Misra et al [6] have studied the viscometric properties of the binary mixtures of tetrahydrofuran with propanol-1 and propanol-2, while Parveen et al [7] have reported on tetrahydrofuran + methanol and + o-cresol. A good number of literature survey shows that some systematic studies are still scarce.…”

“…Earlier workers 12 have reported that there are mainly three types of contribution to the thermodynamic properties. Physical: Due to non-specific van der Waals type dispersive forces leading to a positive contribution towards ∆κ s and E f L and negative contribution towards ∆u.…”

“…The density of various systems has been measured using a single capillary calibrated pyknometer as described earlier. 12 Mixtures were prepared by weighing the liquids in specially designed ground glass stoppered bottles, taking extreme precautions to minimize preferential evaporation. An OHAUS (AR 2140) single pan balance having a stated precision of 0.1 mg was used throughout.…”

Mixed solvents rather than single pure liquids are of utmost practical importance in chemical and industrial processes as they provide an ample opportunity for the continuous adjustment of desired properties of the medium. Therefore, ultrasonic velocity (u) and density (ρ) were measured for the binary mixtures formed by heptane with ethyl acetate or butyl acetate at temperatures 293, 298 and 303 K over the entire composition range. Deviation in ultrasonic velocity (∆u), deviation in isentropic compressibility (∆κ s ), and excess intermolecular free length ( E f L ) have been evaluated using the ultrasonic velocity data and the computed results were fitted to the Redlich-Kister polynomial equation. The values of ∆u, ∆κ s and E f L were plotted against the molar fraction of heptane. The observed positive and negative values of excess parameters were discussed in terms of molecular interaction between the components of the mixtures. Experimental values of ultrasonic velocity and density were compared with the results obtained by theoretical estimation procedures. The results were discussed in terms of average absolute deviation (AAD).

“…The positive values of ∆G * E indicates the presence of strong interaction in butylamine + 1-butanol mixture, whereas negative ∆G * E values for butylamine + tert-butanol mixture may be assigned to the predominance of dispersive forces and also due to less acidic nature of tertiary alcohols than primary alcohols [18]. Gupta et al [19] and Mialkowski et al [20] have also reported similar variations in the ∆G * E values for binary mixtures of ether + alcohols and γ-butyrolactone + dimethylcarbonate. Further, seven empirical relations (Eqs.…”

Density (ρ), refractive index (n), ultrasonic velocity (u), and viscosity (η) were measured for the binary mixtures formed by butylamine with 1-butanol and tert-butanol at temperatures 293, 303, and 313 K over the entire composition range. Excess molar volume V E m , molar refraction deviation ∆R m , deviation in ultrasonic velocity ∆u, viscosity deviation ∆η, and excess Gibb's free energy of activation for viscous flow ∆G * E were derived from the experimental data and the computed results were fitted to the Redlich-Kister polynomial equation. The values of V E m , ∆Rm, ∆u, ∆η, and ∆G * E were plotted against the mole fraction of butylamine. The observed positive and negative values of excess parameters for both the mixtures were explained on the basis of intermolecular interactions present in these mixtures. The higher negative values of V E m and ∆R m and positive values of ∆u, ∆η, and ∆G * E for butylamine + 1-butanol mixture suggest that specific interactions are taking place in butylamine + 1-butanol mixture, while weak dipole-dipole induced forces and dispersive forces seem to be responsible for butylamine + tert-butanol mixture. Furthermore, different empirical relations were used to correlate the binary refractive indices. An excellent agreement was found between experimental and theoretical values.
