Resumo: The original krypton data was reanalyzed at the light of the nonideal behavior exhibited by isotopic rare gas liquid mixtures. Excess molar Gibbs energies of liquid mixtures containing several isotopic forms of krypton were calculated and then used to refine the estimates of vapor pressure ratios between pure isotopic forms in an iterative fashion. It was concluded that in contrast to the case of ammonia, for krypton, deviations from ideal solution behavior do not introduce an important correction when compared with the available data accuracy.
