Prediction of the temperature dependence of the limiting diffusion coefficients of five helium–fluoromethane systems from diffusion coefficients at 300 K and limiting thermal diffusion factors at the same temperature and zero pressure

Abstract

Thermal diffusion factors αT are reported at 300 K for five binary systems consisting of helium and a fluoromethane. The data are extrapolated to zero pressure and used to predict the temperature dependence of the binary diffusion coefficients of these systems.
