The distillation of liquid hydrogen as a means of separating the isotopes H2, HD, and D2 has been known for over twenty years.1 The fractionation of these isotopes is easy by ordinary distillation standards since the relative volatility of any two is quite favorable. Nevertheless, large scale distillation of liquid hydrogen to recover naturally occurring amounts of the heavier isotopes, although considered a number of times,2 has until recently3 been rejected either because of lack of design data, or because of the problems and hazards expected from the operation at 20°K.
