Abstract

Infinite dilution diffusion coefficients of benzothiophene, dibenzothiophene, acridine, naphthalene, and anthracene in tetradecane have been measured in a temperature range from (313.2 to 473.2) K using the Taylor dispersion technique. Predicted values based on the correlations of Wilke−Chang and Tyn−Calus deviate up to 35 %. An Arrhenius type of equation was used to describe the temperature dependence of the diffusion coefficients with an accuracy on average of less than 5 %.
