The binary diffusion of organic vapours such as benzene, nitrobenzene, aniline, n‐hexane, acetone, ethyl alcohol and toluene in H 2 , Ar and N 2 at different temperatures and the diffusion coefficients of the gas pairs; Ar‐O 2 , Ar‐N 2 , Ar‐SO 2 , N 2 ‐NH 3 , N 2 ‐O 2 , N 2 ‐CO 2 & N 2 ‐SO 2 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.
