The present paper discusses the efforts made in HEMRL to establish the synthesis of FOX-7 at 100 g/batch level. In the present study, 1,1-diamino-2,2-dinitroethylene has been synthesised by treatment of acetamidinium chloride with diethylmalonate to obtain 2-methyl-pyrimidine-4,6-dione which on nitration followed by hydrolysis gave FOX-7. The synthesised FOX-7 has been characterized by spectroscopic and thermal techniques. The data obtained confirms the structure of FOX-7. The sensitivity of FOX-7 towards mechanical stimuli indicated its insensitive nature. The theoretically computed explosive and ballistic parameters are close to that of RDX. The synthesised FOX-7 has been used as a precursor for the synthesis of potassium and guanidinium salts and the thermal analysis of these salts indicate their exothermic nature.
本文讨论了高能材料研究实验室（HEMRL）为实现100克/批次规模的FOX-7合成所做的努力。在本研究中，通过用丙二酸二乙酯处理氯化乙脒来合成1,1-二氨基-2,2-二硝基乙烯，以获得2-甲基嘧啶-4,6-二酮，该产物经硝化然后水解得到FOX-7。合成的FOX-7已通过光谱和热分析技术进行了表征。所获得的数据证实了FOX-7的结构。FOX-7对机械刺激的敏感性表明其钝感特性。理论计算的爆炸和弹道参数与黑索今（RDX）相近。合成的FOX-7已被用作合成钾盐和胍盐的前体，对这些盐的热分析表明它们具有放热性质。
