Measurement of binary diffusion coefficient of gases and organic vapours by chromatography

Abstract

The binary diffusion of organic vapours such as benzene, nitrobenzene, aniline, n‐hexane, acetone, ethyl alcohol and toluene in H2, Ar and N2 at different temperatures and the diffusion coefficients of the gas pairs; Ar‐O2, Ar‐N2, Ar‐SO2, N2‐NH3, N2‐O2, N2‐CO2 & N2‐SO2 at 25°C have been studied using a gas chromatograph (GCHF‐18). Good agreement was found between observed and theoretically calculated values of diffusion coefficients. Copyright © 1981 Canadian Society for Chemical Engineering
