Abstract
Steady‐state separation factors of 1:1 carbon dioxide—nitrous oxide mixture at mean temperatures 363°, 401.5°, and 435.5°K and at pressures ranging from 0.30 to 0.95 atm have been measured by operating a coaxial thermal‐diffusion column. It has been found that the variation of separation factor with pressure agrees qualitatively with Furry—Jones' theory for isotopic mixtures. A detailed comparison of the experimental results with the theory has been made on the Maxwellian and Lennard‐Jones (12:6) models and values for the thermal‐diffusion factor for this polyatomic gas mixture have been estimated.
