NO-HN03 Exchange System for Production of 14N Highly Depleted of 15N
The isotopic exchange reaction between NO and HNO 3 was used to prepare 14 N highly depleted 15 N. This required an efficient reflux system of low holdup to convert oxides of nitrogen to nitric acid by reaction with oxygen and water. A study of the characteristics of the one constructed showed that...

was used to prepare
14
N highly depleted
15
N. This required an efficient reflux system of low holdup to convert oxides of nitrogen to nitric acid by reaction with oxygen and water. A study of the characteristics of the one constructed showed that less than 1 part in 32,000 of the nitric acid was lost from the refluxer as oxides of nitrogen.
14
N with an atom fraction of less than 0.00004 of
15
N was prepared at the rate of 46.0 g/day. The application of the refluxer to a system for producing
15
N is discussed. |
