ABSTRACT:
A catalyzed process for deuterium isotope enrichment by H-D exchange between an amine and hydrogen in which the exchange catalyst includes a mixture of Group I and Group II metal amides. Catalyst mixtures of potassium methylamide with beryllium, calcium or strontium methylamide are of particular interest. Resistance to hydride formation is equivalent to the binary Group I metal amide catalysts and higher H-D exchange rates can be achieved with some combinations.
