“…Similar results were observed in the mixtures of TEA alcohols [13]. No significant change in π Further, the refractive index and density of the mixtures were correlated using the empirical/semi--empirical relations and models as reported earlier [7,8] Table IV that HBT model is more suitable than the Rackett model for the prediction of density of the binary mixture of THF + methanol. However, in case of THF + o-cresol mixture, these models could not be applied due to non-availability of data of critical volume.…”

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.

“…The Rackett and Hankinson-Brobst-Thomson (HBT) models 8,9 have been applied to compare the difference between predicted and experimental density. Vangeel's, Nomoto's and Junjie's relation and Collision Factor Theory (CFT) 10 were also used to correlate the ultrasonic velocity data. The results have been discussed in terms of average absolute deviation (AAD).…”

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).

“…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.…”
