【Abstract】 The RbDNBF (rubidium 7-hydroxy-4, 6-dinitro-5,7-dihydrobenzofuroxanide) is synthesized by reacting sodium salt of DNBF and rubidium nitrate solution. The molecule structure is characterized by IR and the thermal decomposition process is studied by DSC and TG-DTG. The sensitivity properties of RbDNBF are tested by various sensitivity apparatus. The results demonstrate that the bulk density of RbDNBF is higher than that of KDNBF(Potassium 7- hydroxy-4,6-dinitro-5,7-dihydrobenzofuroxanide) and the free-flowing property is also better than that of KDNBF. From 189 ℃ to 236 ℃, the thermal decomposition process occurs with the peak temperature at 210 ℃. The mass percent of solid residue is up to 25%. The sensitivity results show that the sensitivity properties of RbDNBF are equivalent with that of KDNBF.更多还原
