Abstract
The paper discusses the synthesis, characterisation, and performance evaluation of diarylfuroxans namely, bis-phenyl-3,4-furoxan (5) and bis-(4’-nitrophenyl)-3,4-furoxan (6). The
molecules have been synthesised on the lines of reported method by cyclodimerisation of the
nitrile oxides generated from benzaldoxime and p-nitro benzaldoxime, respectively. The synthesised
furoxans (5 ) and (6) were characterised by the elemental analysis, UV, IR, and 1H NMR
spectroscopy. The hazard characteristics (impact and friction sensitivity) confirm that the
compounds are safe to handle. The oxygen balance, velocity of detonation and detonation
pressure have been computed. The detonation velocity and pressure along with oxygen balance
increased with the substitution of nitro group in the benzene ring, as expected. The
thermogravimetric studies on promising compound (6) brings out that maximum weight loss
occurs at decomposition temperature of 259–260 °C.
