Thermoacoustical parameters have been computed for ab inary system of cyclohexane + cyclohexanol at three different temperatures. These parameters have been employed to compute available volume by using twodifferent approaches, thermoacoustical and ultrasonic. Furthermore non-linearity parameter, B/A,has also been computed by four different approaches. The excess counterparts of the non-linearity parameter have also been computed. A Comparative study has then been carried out which might shed some light on the molecular interactions PACS no. 43.25.-x, 43.25.Ba 8 ©S.Hirzel Verlag · EAA Dey, Kumar: Computation of liquid papameters ACTA ACUSTICA UNITED WITH ACUSTICA Vol. 96 (2011)

“…[5] Chlorotoluenes are used as intermediates in manufacturing pesticides, pharmaceutical formulations and dyes. [6] Excess thermodynamic properties for the binary mixtures of cyclohexanol with dimethylsulphoxide, [5] water, [7] 1,2-dichloroethane [8] and cyclohexane [9,10] have been reported in the literature. However, literature survey reveals that no study on excess thermodynamic properties for the systems containing cyclohexanol with chlorotoluenes was reported.…”

Densities (ρ) at different temperatures from 303.15 to 318.15 K, speeds of sound (u) and viscosities (η) at 303.15 K were measured for the binary mixtures of cyclohexanol with 2-chlorotoluene, 3-chlorotoluene and 4-chlorotoluene over the entire range of composition. The excess volumes (V E ) for the mixtures have been computed from the experimental density data. Further, the deviation in isentropic compressibilities (Δκ s ) and deviation in viscosities (Δη) for the binary mixtures have been calculated from the speed of sound and viscosity data, respectively. The V E values and Δκ s values were positive and Δη data were negative for all the mixtures over the whole range of composition at the measured temperatures. The calculated excess functions V E , Δκ s and Δη were fitted to RedlichKister equation. The excess functions have been discussed in terms of molecular interactions between component molecules of the binary mixtures.

The static dielectric constant (permittivity), ε, and the molar volume of supercritical, homogeneous mixtures of methane and methanol were measured at 323 K and 398 K from 50 to 200 MPa over the whole composition range between pure methane and pure methanol. Both quantities were determined simultaneously with the same samples in one autoclave which served as high pressure dilatometer and capacitor. At 398 K and 200 MPa ε increases from 1.53 (methane) to 23.2 (methanol). The measured mixture ε‐values are always below the linear interpolation line. Excess volumes of the mixtures are negative. At constant composition and temperature, ε always increases linearly with increasing density. With the Onsager‐Kirkwood‐Fröhlich relation, dielectric correlation factors, g, have been derived. At constant T and P the g‐values as function of composition give an s‐shaped curve from methane (g = 1) to methanol (g ≈ 2.6). This polar‐nonpolar supercritical combination is one of the very few systems for which the dielectric behaviour in dependence of temperature, total density and the complete concentration range could be studied.
