摘　　要：硝酸铷与DNBF(4,6二硝基5,7二氢化苯并氧化呋咱)的钠盐反应,制得了标题化合物RbDNBF(7羟基4,6二硝基5,7二氢化苯并氧化呋咱铷盐)。通过IR对其分子结构进行了表征,利用DSC和TGDTG研究了其热分解过程,并对其感度性质进行了测试。研究表明:RbDNBF的假密度高于DNBF的钾盐(KDNBF),流散性好;在189～236℃范围内发生热分解,峰顶温度为210℃,固相残渣含量为25%;它的感度性能与KDNBF相当。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 IB and the thermal decomposition process is studied by DSC and TG-DTG. The sensitivity properties of BbDNBF are tested by various sensitivity apparatus. The results demonstrate that the bulk density of BbDNBF is higher than that of KDNBF （Potassium 7-hydroxy-4,6-dinitro-5,7-dihydrobenzofuroxanide） and the free-glowing 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 resuhs show that the sensitivity properties of BbDNBF are equivalent with that of KDNBF.
