Abstract
This paper reviews the recent work done on the synthesis as well as characterization of dinitrogen pentoxide (DNPO). The physico-chemical characteristics of DNPO are also discussed. The review brings out the key aspects of N2O5 technology with relevance to realize modern and novel HEMs. The paper also includes the aspects related with establishing the synthesis facility of dinitrogen pentoxide at HEMRL by gas phase interaction of N2O4 with O3. The process parameters for the synthesis of N2O5 at 50 g/batch have been optimized. The synthesized dinitrogen pentoxide has been characterized by UV [204, 213, 258 nm (Ï â Ï*) 378 and 384 nm (n â Ï*)] and IR (1428, 1266, 1249, 1206, 1044, 822, 750, 546 and 454 cmâ1) spectroscopy. The DSC clearly showed the sublimation of N2O5 at 32 °C. The nitration studies on 2,6,8,12-tetraacetylhexaaza tetracyclo[5,5,0,03,1105,9]dodecane (TAIW) proved its viability in 2,4,6,8,10,12-hexanitro-2,4,6,810,12)-hexaazatetracyclo [5,5,0,03,1105,9]dodecane (CL-20) synthesis. The synthesized CL-20 and its precursors have also been subjected to hyphenated TG-FTIR studies to understand decomposition pattern.
