Ultrasonic velocity, permittivity, density, viscosity and proton nuclear magnetic resonance measurements of binary mixtures of benzonitrile with organic solvents

Ultrasonic, Volumetric and Isentropic Compressibility of Binary Mixtures of 1,4-Dioxane with Primary Alcohols at 303.15 K

“…Quantitatively as per the absolute reaction rate theory [34] [35] the deviation of the viscosities (Δη) from the ideal mixture values are calculated as [36] [ ] We have calculated excess viscosity, excess molar volume and excess isentropic compressibility at 303.15 K for the binary mixture of 1,4-dioxane (1) with the primary alcohols (2). The variation of the excess properties over the entire range of compositions for the binary mixtures is depicted in Figures 1-3.…”

Densities and viscosities of binary mixtures of {dimethylsulfoxide+aliphatic lower alkanols (C1–C3)} at temperatures from T=303.15K to T=323.15K

“…The deviations of the viscosities from the ideal mixture values (i.e., excess viscosities) can be calculated as [34,35]:…”

Viscometric studies of binary liquid mixtures of cyclopentane (1)+branched alkanols (2) at T=(298.15 and 308.15) K

“…These different expressions on ideal mixing law for viscosity have been chosen erroneously and often unknowingly have been used by various workers [14][15][16][17][18][19][20][21]. These different expressions give rise to different values of deviations in viscosity which may lead to the improper estimation of results which may not be correct.…”

“…Sometimes the deviations in viscosity [18,19] are given by expression Table 3 Coefficients A i and standard deviations σ for least-squares representations by Eq. (1) at various temperatures.…”
