Thermal diffusion in the n-heptane–benzene system at 25°C

Abstract

Thermal diffusion factors and heats of transfer have been determined for liquid mixtures of n-heptane and benzene over a wide range of concentrations at 25 °C. A pure Soret effect cell, with a liquid layer less than 1 mm thick, was used. The results agree well with some recently published data obtained by Korsching using a different method.
