Liquid diffusion of nonelectrolytes: Part I

Abstract

tion coefficient theories. The predictions are compared with the experimental results throughout the review. Part I will be followed by Part I1 in November reviewing self-diffusion, empirical predictive equations, and experimental techniques. A supplement of critical tabulations of all experimental diffusion data since 1956 has been prepared.

Use of Taylor dispersion for the measurement of probe diffusion in polymer solutions

“…It has been found that the Stokes-Einstein equation faits when the solute size (radius) is less than five times that of the solvent (Chen et al, 1981). This supports the observation that values of Stokes radii calculated from 33 and the Stokes-Einstein equation can differ from the actual van der Waals radius of the molecule (Ghai et al, 1973). Significant effort, both from a theoretical and empirical standpoint, has been placed on improving upon the predictive capability of the Stokes-Einstein equation.…”

Rate constants for the bimolecular self‐reaction of tertbutyl radicals in nalkane solvents

“…The subject of diffusion in liquid nonelectrolytes has been reviewed recently [30]. There are a number of semiempirical relations designed for estimates of diffusion coefficients from viscosities which have been tested with variable success.…”

Electromigration diffusivity spectrometry: A way for simultaneous determination of diffusion coefficients from mixed samples

“…Table 2 shows a comparison between the two approaches; Eq. (12) gives undoubtedly the better results (see also Table 1) than Eq. (11).…”
