Abstract

1312191 Isotopic enrichment of ammonia COMMISSARIAT A L'ENERGIE ATOMIQUE 19 April 1971 [10 Feb 1970] 21397/71 Addition to 1125670 Heading C1A A process for the isotopic exchange of hydrogen and deuterium comprises contacting deuterium-containing hydrogen and liquid ammonia in the presence of a tertiary amine, other than trimethylamine, of the formula wherein R, R<SP>1</SP> and R<SP>11</SP> are aliphatic radicals containing 1-4 carbon atoms. Triethylamine and tripropylamine are preferred tertiary amines. Potassium amide may be used as a catalyst for the exchange.
