Prediction of diffusivities in liquids
A comprehensive review is given of the existing approaches to the prediction of binary diffusivities in liquids and the problems encountered in ternary mixtures. A new functional group contribution method is presented allowing a reasonably good prediction (usually less than 5 % error) on the basis of group molecular diffusion areas and activation energies. Even complex industrially used systems (DMSO or Sulfolane/aromatics) can be handled successfully including also compounds like water and alcohols.
