Thermal Diffusion in Binary Liquid Mixtures of Molecules of Simple Symmetry

摘要

A singlehyphen;stage twohyphen;cell apparatus for measuring thermal diffusion in liquid mixtures has been developed. Thermalhyphen;diffusion measurements are presented for a series of binary mixtures of molecules of simple symmetry over a range of temperature from 5deg;mdash;55deg;C. The theory presented in a previous paper applies quite satisfactorily. The results indicate that the proposed measure of the cohesive energyHiequals;Tpart;ppart;TiVminus;Tpart;Vpart;Ti,gives reasonably quantitative results.
