Synthesis and Characterization of Picrylfurazanether Compounds

为了得到综合性能优良的高能量密度材料,通过将羟基硝基呋咱转化为相应的醇钠盐,分别与苦基氯(PcCl)和2,4-二氯-1,3,5-三硝基苯(DCPc)缩合得到苦基-(3-硝基呋咱基-4)醚(FOP)和双(3-硝基呋咱基-4)苦基醚(DFOP),采用红外光谱、核磁共振、质谱及元素分析方法对其结构进行了表征。确定了最佳合成条件,FOP合成条件为:PcCl与硝基呋咱醇钠的摩尔比1.0:1.1,反应温度80℃,反应时间16h,以原料PcCl计产品收率达到31%以上;DFOP合成条件为:DCPc与硝基呋咱醇钠的摩尔比1.0:2.7,反应温度80℃,反应时间2h,以原料DCPc计产品收率达到42%以上。

In order to obtain high energy density materials with excellent synthetic performances, picryl （3- nitrofurazan-4） ether（FOP） and bis （3-nitrofurazan-4） picryl ether（DFOP） were synthesized by condensation of sodium hydroxyl nitrofurazan with picryl chloride （PcCl） and 2, 4-diehloro-1, 3, 5-trinitrobenzene （DCPc）, respectively. The products were characterized by FTIR, 13^H NMR, 13^C NMR, MS and elemental analyses. The optimal reaction conditions obtained are..FOP of the yield as 31% from PcCl,the mole ratio of PcCl to sodium nitrohydrofurazan 1.0 ： 1. 1, reaction temperature 80℃, reaction time 16h, and for DFOP of the yield as 42% from DCPc,the mole ratio of DCPc to sodium nitrohydrofurazan 1.0 ： 2.7, reaction temperature 80℃, reaction time 2 h.
