In situ generated amine as a Lewis base catalyst in the reaction of 3,7‐dinitro‐1,3,5,7‐tetraazabicyclo[3.3.1]nonane in nitric acid: Experimental and DFT study
Abstract:The problem how ammonium nitrate affects the nitrolysis of 3,7‐dinitro‐1,3,5,7‐tetraazabicyclo[3.3.1]nonane (DPT) in nitric acid to prepare 1,3,5,7‐tetranitro‐1,3,5,7‐tetraazacyclooctane (HMX) has puzzled chemists for decades. In this paper, experimental work and theoretical calculation are described to investigate the long‐standing challenge. The experiment results showed that ammonium nitrate or alkylammonium chlorides were in favor of the formation of 1‐nitroso‐3,5,7‐trinitro‐1,3,5,7‐tetraazacyclooctane (MN… Show more
