以2,4,6-三硝基氯苯为原料, 经过叠氮化、脱氮环化和异常亲核取代氢(VNS)反应合成了4,6-二硝基-5,7-二氨基苯并氧化呋咱(CL-14), 三步总收率达到50.3%, 并采用红外光谱、核磁共振光谱、元素分析等进行了结构表征|确定了合成CL-14的最佳VNS反应条件: 以盐酸羟氨作为VNS试剂, 20～40 ℃下反应6 h, 收率达到60%(文献值53%). 研究结果表明, CL-14具有良好的感度特性和热安定性, 其撞击感度与中间产物4,6-二硝基苯并氧化呋咱(DNBF)基本相当, 而其摩擦感度远低于其DNBF|DSC和TG-DTG实验发现, CL-14仅有一个分解过程, 其分解峰温为308.52 ℃.

4,6-Dinitro-5,7-diamino benzenfuroxan (CL-14) was synthesized from 2,4,6-trinitrchloroben- hzene through the process of azidcation, denitrogenation and vicarious nucleophilic substitution (VNS) reaction with total yield of 50.3%, and the structures of CL-14 and main intermediates were characterized by IR, NMR spectra and elemental analysis. The conditions of VNS reaction were optimized, and the optimal reactive conditions were obtained as follows: NH2OH•HCl was VNS reagent, the reactive time was 6 h at 20～40 ℃, and the yield was reached to 60%. The experimental results showed that there were favorable mechanical sensitivities and thermal stability of CL-14, which friction sensitivity was better than that of DNBF. DSC and TG-DTG measurements indicated that there was only one decomposition process of CL-14 with exothermic peak temperature of 308.52 ℃.
