PRELIMINARY STUDY OF THE FRACTIONATION OF ISOTOPIC ISOMERS BY DISTILLATION
Keyword(s):
Slight separations of some isotopic isomers have been achieved by equilibrium rectification. In the case of chlorine the total separation amounted to 0.048 atomic weight units; 28.6% of the O18 has also been removed from normal oxygen by the fractionation of water, and in a short run with liquid oxygen the normal concentration of O18 has been raised from 0.2% to 0.25%. The last-mentioned separation can be carried considerably further with present equipment.CH3D was synthesized. Its boiling point appears to be 0.5 °C. lower than that of methane.The vapor pressures of a 56.8% solution of D2O were measured, and it is suggested that the published values of the vapor pressure of D2O at temperatures lower than 40 °C. may be slightly too high.
