In this research, the RDX yield from nitrolysing hexamethylenetetramine (hexamine, HA) together with methylenedinitramine (MDNA) in 90% nitric acid was more than 100%. It was found that MDNA decomposed completely in 90% nitric acid, forming O(CH 2 ONO 2 ) 2 , while in HNO 3 NH 4 NO 3 system the decomposed fragments of MDNA condensed into RDX. On the basis of the comparison of the experimental results to the 1 H‐NMR spectra obtained by following the decomposition reaction of MDNA with nitric acid, the intermediate, HOCH 2 NHNO 2 , was postulated as one of the possible precursors to RDX both in Hale and in K process.
