摘要:
实验室直接制备的7-氨基-4,6-二硝基苯并氧化呋咱的含酸量较高，而炸药的酸度较高非常不利于使用及储存，所以需要对其进行进一步的精制除酸才能安全使用。该文研究采用甲醇、N,N二甲基甲酰胺（DMF）、二甲亚砜（DMSO）3种溶剂对粗品进行精制，并研究了精制后的样品在含酸量、粒度、微观形貌、机械感度及热安定性方面的性能改变。试验表明，采用甲醇除酸效果最好：精制后的样品pH值为6.6；样品颗粒的尺寸最小，粒度主要分布在0.4～30.0μm，但存在少量的团聚现象；撞击感度和摩擦感度分别为28%和20%；真空安定性测试表明100 ℃时，真空放气量为0.047 mL/g，200 ℃时为0.85 mL/g；24 h的热质量损失率为0.80%。
Abstract:
Because high acid content in laboratoryprepared 7-amino-4,6-dinitrobenzofuroxan (ADNBF)is not conducive use and storage,it is necessary to remove the acid from the explosive before use.CH-3OH、DMF、DMSO were chosen as solvents to recrystallize ADNBF.The properties of ADNBF after purification in aspects of acid content, particle size, morphology, mechanical sensitivity and thermal stability were tested.Experimental results show that the deacidification of CH-3OH works best:pH value of 6.6 after purification; smallest sample size particles, particle size mainly in 0.4~30.0μm, but there are some agglomeration; impact sensitivity and friction sensitivity of 28% and 20%, respectively; the gas volume in vacuum at vacuum stability tests being 0.047 mL/g at 100℃and 0.85 mL/g at 200℃; The thermal gravity loss being 0.80% in 24 hours.
