摘要：The paper discusses the synthesis, characterisation, and performance evaluation of diaryl furoxans 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.
