Measurement of Density and Viscosity of Binary 1-Alkanol Systems (C₈−C₁₁) at 101 kPa and Temperatures from (283.15 to 313.15) K

Abstract

In this paper, we present the experimental values of the density and dynamic viscosity, obtained at 101 kPa, for binary systems containing 1-octanol, 1-nonanol, 1-decanol, and 1-undecanol over the entire range of mole fractions and at the following temperatures: (283.15, 288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K. The experimental viscosity data have been correlated by means of a model previously developed in our group. The binary interaction parameters of this model are also presented. The agreement between experimental and calculated values is quite good. The overall mean relative standard deviations are 0.2 % for the system 1-octanol + 1-nonanol, 0.5 % for the system 1-octanol + 1-decanol, 0.7 % for the system 1-octanol + 1-undecanol, 0.2 % for the system 1-nonanol+1-decanol, 0.6 % for the system 1-nonanol + 1- undecanol, and 0.2 % for the system 1-decanol + 1-undecanol.

Study of molecular interactions in binary liquid mixtures of 1-octanol with n-hexane, n-octane, and n-decane using volumetric, viscometric, and acoustic properties

“…The measured densities (q), viscosities (g), and speeds of sound (u) of pure components at the aforementioned temperatures are compared with the literature values [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] in table 1.…”

Excess Volumes, Densities, Speeds of Sound, and Viscosities for the Binary Systems of 1-Octanol with Hexadecane and Squalane at (298.15, 303.15 and 308.15) K

“…The estimated purities determined by gas chromatographic analysis were better than 99.5 mol % for all the liquid samples. Furthermore, the purities of the liquids were checked by comparing densities, ρ, viscosities, η, and speeds of sound, u, with corresponding literature values [11,14,[20][21][22][23][24][25][26][27][28][29][30], as reported in Table 1.…”

Thermophysical and sonochemical behaviour of binary mixtures of decan-1-ol with halohydrocarbons at (T=293.15 and 313.15)K

“…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 [1][2][3][4][5][6][7][8][9][10]. 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 [11][12][13][14][15][16][17][18][19][20][21][22][23].…”

“…The excess molar volumes were reproducible to ±2 Á 10 À3 cm 3 Á mol À1 . The first term in equation (2) represents the actual volume of the mixture, V mix and the second, the volume it would occupy if the mixture behaved ideally, V id . The following relations have been used to calculate the sound velocity, u, of the binary liquid mixtures:…”
