Nitrogen(V) Oxide (Nitrogen Pentoxide, Dinitrogen Pentoxide, Nitric Anhydride)

Establishment of process technology for the manufacture of dinitrogen pentoxide and its utility for the synthesis of most powerful explosive of today—CL-20

“…Solid N 2 O 5 can be prepared on a laboratory scale by the reaction of chlorine with solid silver nitrate as well as during the reaction of nitryl chloride/fluoride with metal nitrate and by the dehydration of nitric acid by phosphoric oxide [9,10]. However, these methods produce low yields of poor quality product contaminated with N 2 O 4 and small quantities of HNO 3 .…”

“…A series of nitrated products, namely octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo [5,5,0,0 3,11 0 5,9 ]dodecane (CL-20) 1,3,3-trinitro azetidine (TNAZ), octanitrocubane (ONC), ammonium dinitramide (ADN) and hydrazinium nitroformate (HNF), are key HEMs. The selection of a nitrating agent for a particular nitration reaction is mainly dependent on the chemical nature of substrate molecule.…”

N-Nitropyridinium Nitrate: An Efficient Nitrating Agent for the Synthesis of 2-[Butyl(nitro)amino]ethyl Nitrate (n-BuNENA)

“…Dinitrogen pentoxide [21] and ionic liquid [22] were synthesized and N-nitropyridinium nitrate was prepared according to a literature method [23]. IR spectra were recorded on a Perkin Elmer FT-IR Spectrometer, usually as a neat sample.…”
