An experimental study is described on the effect of liquid properties on axial dispersion in packed beds. Working with water between 278 and 373 K, the range 57600). A representation of Pe L vs. Pe m reveals the existence of a very flat minimum (typically 10 2 700, but it increases significantly with a decrease in Sc, for Sc<700. The experimental data used to test available correlations for predicting D L show that they are inaccurate over considerable ranges of the variables.
