Ternary Diffusion Coefficients of Cyclohexane + Toluene + Methanol by Taylor Dispersion Measurements at 298.15 K. Part 2. Low Toluene Area Near the Binodal Curve

Abstract

The concentration dependence of the mutual diffusion coefficients in the ternary liquid mixture cyclohexane (1) + toluene (2) + methanol (3) is determined at 298.15 K by the Taylor dispersion technique along three concentration paths of a constant toluene mole fraction of x2 = 0.05, x2 = 0.10, and x2 = 0.20, ranging from the binary subsystems toward the liquid−liquid phase boundary of the ternary system. The four elements of the matrix of mutual diffusion coefficients, the corresponding eigenvalues, and the determinant of the matrix are given.
