“…It is due to the fact that -OH group attached to the benzene ring in case of o-cresol is stabilized to a greater extent through resonance as compared to alcoholic -OH group of methanol. Similar results of ∆R m and ∆u have been reported earlier [10][11][12].…”

“…The values of APD for refractive index and root mean square deviation for density are given in Tables III and IV The values of ∆R m , ∆u, π plained as a result of cumulative manifestation of various types of intermolecular interactions between components. It has been reported earlier [10] that the excess thermodynamic properties of the mixtures are influenced by three main types of contribution, viz. (i) physical: due to non-specific Van der Waals type forces; (ii) chemical: due to hydrogen bonding, dipole-dipole, and donor-acceptor interaction between unlike molecules; (iii) structural: due to the fitting of smaller molecules into the voids created by the bigger molecules.…”

The refractive indices, densities and ultrasonic velocities of binary liquid mixtures of tetrahydrofuran (THF) with methanol and o-cresol over the entire composition range have been measured at 293, 303 and 313 K. Refractive index, density and ultrasonic velocity data have been used to evaluate the molar refraction deviation ∆R m , deviation in ultrasonic velocity ∆u, excess internal pressure π These results suggest that specific strong interactions are taking place in THF + o-cresol mixture while dispersive forces seem to be responsible for behaviour of THF + methanol mixture. Further, experimental refractive index and density data of these mixtures were also used to test the validity of the empirical/semi-empirical relations and models for refractive index and density, respectively.

“…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.…”

Specific heat ratio (γ), pseudo-Grüneisen parameter (Γ ), heat capacity (C p ) and effective Debye temperature (θ D ) for binary system of tetrahydrofuran with o-cresol and methanol respectively, were calculated using the experimentally measured densities, velocities and viscosities of the pure liquids and their mixtures over the whole composition range and at T = 293, 303, 313 K. The excess pseudo-Grüneisen parameter (Γ E ), excess molar isentropic compressibility (K E s ) and excess acoustic impedance (Z E ) were also calculated. The excess deviation functions have been correlated using Redlich-Kister polynomial equation. The observed values of the excess parameters plotted against the mole fraction of tetrahydrofuran have been explained on the basis of intermolecular interaction suggesting strong interaction in tetrahydrofuran + o-cresol than in tetrahydrofuran + methanol. Partial molar isentropic compressibility at infinite dilution and their excess values were calculated for each component. Sanchez theory, Goldsach-Sarvas volume fraction statistics, Sudgen's relation, Flory-Patterson-Rastogi and Brock and Bird model were used with the Aurebach relation to compute theoretically the values of ultrasonic velocities at varying temperatures. The velocity deviations were estimated in terms of average percentage deviations. Internal pressure for both the systems were calculated theoretically and discussed on the basis of relative applicability of the models in theoretical estimations. The isothermal compressibility (k T ), for these binary mixtures were theoretically evaluated by using the Flory statistical theory and five hard sphere models and compared with the experimental values.
