Ternary Diffusion Coefficients of Cyclohexane + Toluene + Methanol by Taylor Dispersion Measurements at 298.15 K. Part 1. Toluene-Rich Area

Abstract

The concentration dependence of the mutual diffusion coefficients in the ternary liquid mixture cyclohexane + toluene + methanol is determined at 298.15 K by Taylor dispersion technique along two concentration paths of a constant toluene mole fraction of x 2 ) 0.40 and x 2 ) 0.60, respectively. The four elements of the matrix of mutual diffusion coefficients, the eigenvalues, and the determinant of the matrix are given.

Investigation of Fickian diffusion in the ternary mixture of 1,2,3,4-tetrahydronaphthalene, isobutylbenzene, and dodecane

“…Consequently, they are not comparable with our present results and we do not further analyze them here. Regarding non-hydrocarbon ternary liquid mixtures, there exist several recent experimental investigations, [3][4][5][6][7] due to the different nature of the system they also are not comparable with our present results.…”

“…But the liquids appearing in nature and in industrial applications are essentially multicomponent, a fact that leads research focus to move lately to diffusion in multicomponent liquid systems, starting with ternary mixtures. [1][2][3][4][5][6][7][8][9][10] However, mainly due to experimental and mathematical difficulties, even in ternary mixtures, diffusion coefficients are so far available only for a very limited number of these systems. Furthermore, in those cases where more than one data exist, quite often measurements by different experimental groups or by different techniques do not agree.…”

“…The Taylor dispersion method for diffusion measurements in multicomponent systems [7][8][9][10][11][12][13][14][15] is based on the dispersion of small amounts of solution injected into laminar carrier streams of solvent or solution of different concentrations, flowing through a long capillary tube with the length and radius accurately measured (in our case, they are 3.2799 (±0.0001) Â 10 4 mm and 0.5570 ± (0.0003) mm, respectively [12][13][14][15]). …”

Diffusion coefficients of nickel chloride in aqueous solutions of lactose at T=298.15K and T=310.15K

“…The theory of the Taylor dispersion technique is well described in the literature [28][29][30][31][32][33][34][35][36][37], and so the authors only indicate some relevant points concerning this method on the experimental determination of binary diffusion coefficients and ternary diffusion coefficients, respectively.…”
