Abstract

Abstract: 2,4,6-Trinitro-2,4,6-triazacyclohexanone could be synthesized via the condensation of the nitrolytic fragments of DPTand urea (or nitrourea) in the nitrolytic medium.In this paper the nitrogen atoms in different positions of DPTwere labelled with ¹⁵Natoms respectively.With the help of ¹⁵N NMRspectra, the isotope distribution and abundance of ¹⁵Nlabelled atoms in the product and re-actant molecules could be determined.The results indicate that the nitrolytic fragments condensed with urea (or nitrourea) are N,N-dihydroxymethylamines without the nitro-substituent, and there exists a exchanging process between the nitro-groups in the nitrourea and in the nitrolysis agent.

Key words: Azacyclohexanone, ¹⁵N NMR, Labelled atom, Reaction mechanism
