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.
The concentration dependence of the mutual diffusion coefficients in the ternary liquid mixture glycerol + acetone + water is determined at 298.15 K by the Taylor dispersion technique. As a continuation of previous measurements, we selected three concentration paths of a constant water mole fraction of x 3 ) 0.1, 0.2, and 0.3, respectively, ranging from the limit of the binary subsystem toward the phase boundary in the ternary system. The eigenvalues and the determinant of Fick's diffusion coefficient matrix are given.
The concentration dependence of the mutual diffusion coefficients in the ternary liquid mixture glycerol + acetone
+ water is determined at 298.15 K by the Taylor dispersion technique along two concentration paths of a constant
water mole fraction of x
3 = 0.60 and 0.80, respectively. The eigenvalues of Fick's diffusion coefficient matrix
are given. The present paper is a continuation of part 1 with measurements along concentration paths in the
vicinity of the critical solution point and of part 2 in the acetone-rich region.
