13N- ammonia manufacturing method and apparatus

摘要

PROBLEM TO BE SOLVED: To provide a producing method and device for ¹³N-ammonia easily producible of ¹³N-ammonia without using defective ion exchanger resin so that the in-target method is widely used. ;SOLUTION: A producing device 10 for ¹³N-ammonia is provided with a heating reaction vessel 1 containing produced target liquid and a target liquid introducing pipe 2 to introduce the target liquid containing ¹³N-ammonia from the target vessel to the heating reaction vessel 1. Also, an alkali supply pipe 3 is provided to supply the heating reaction vessel 1 with an alkali solution so as to separate ¹³N-ammonia from the target liquid. Besides, provided are, a transport pipe 4 to transport the separated and purified ¹³N-ammonia from the heating reacting vessel 1 and a solution draining pipe 6 to drain the remaining solution from the reaction vessel 1 after separation and purification.;COPYRIGHT: (C)1997,JPO
