Abstract
By use of thermal diffusion columns, the N2–H2 system has been separated continuously and its thermal diffusion ratio α has been determined with a method of least ambiguity under a pressure range of 1∼12.6 atmos. The α‐values thus obtained, based on the Furry‐Jones theory of the apparatus, have been found to be not constant and also to differ very much in most cases from those hitherto reported. However, the values corrected according to the theory modified by Drickamer et al. have been shown to be reasonable, supporting their modified theory.
