Acoustical and Excess Properties of {Chlorobenzene + 1-Hexanol, or 1-Heptanol, or 1-Octanol, or 1-Nonanol, or 1-Decanol} at (298.15, 303.15, 308.15, and 313.15) K

Abstract

Isentropic compressibility k s , excess isentropic compressibility k s E , excess molar volume V E , viscosity deviations ∆η, and speed of sound deviations u D for {chlorobenzene + 1-hexanol or 1-heptanol, or 1-octanol, or 1-nonanol, or 1-decanol} binary mixtures at temperatures ranging from (298.15 to 313.15) K and at atmospheric pressure were derived from experimental viscosity η, density F, and speed of sound u data. The calculated excess and deviation functions were further fitted to the polynomial relation to estimate the coefficients and standard errors. While the experimental viscosity data was compared with the predicted values obtained from empirical expressions, the speeds of sound data was analyzed in term of Schaaffs' collision factor theory and Jacobson's intermolecular free length theory of solutions. The effects of n-alkan-1-ol chain length as well as the temperature on the excess molar volume were studied.

Density, Viscosity, Refractive Index, and Speed of Sound in Binary Mixtures of Pyridine and 1‐Alkanols (C6, C7, C8, C10) at 303.15 K

“…6 All the purified chemicals were stored over 0.4 nm molecular sieves to reduce the moisture content, if any, and were degassed before use. Further, the purities of these solvents were ascertained by comparing the measured ρ, η, n D and u values at 303.15 K with the available literature values, [7][8][9][10][11][12][13][14][15] as shown in Table 1. Mixtures were prepared by mass in a dry box 13 using a Precisa XB-220 A (Swiss make) electronic balance having an accuracy of ±0.1 mg.…”

“…The variations in the volumetric and acoustic properties of binary mixtures of alkanols containing haloalkanes, acetonitrile, ethylacetate, and ethenyl ethanoate, with the molecular size, shape, chain-length, and degree of molecular association of normal alkanols and branched alkanols have been reported earlier [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Alkanols are polar and self-associated liquids, and the dipolar association of alkanols decreases when they are mixed with polar compounds containing halogen atoms, due to some sort of specific intermolecular interactions between the hydroxyl oxygen of alkanols and the haloalkanes [16][17][18][19][20][21][22][23].…”

“…An electronic digital stopwatch with an uncertainty of ± 0.01 s was used for flow time measurements. The experimental uncertainty of viscosity was estimated as ±1.03% and the uncertainty of temperature ± 0.1 K. The purity of all these solvents were compared with the measured densities, speeds of sound and viscosities of the pure liquids with the literature [13][14][15][16][17][18][19][20][21] and these were enlisted in Table 2.…”
