摘　　要：研究了一种高安全性合成1,1–二氨基–2,2–二硝基乙烯（FOX–7）的方法,以盐酸乙脒与乙二酸二乙酯为原料,经环化反应合成了2–甲氧基–2–甲基–4,5–咪唑烷二酮,再用硝硫混酸硝化得到2–（二硝基亚甲基）–4,5–咪唑烷二酮,水解反应得到了FOX–7,总收率为56.7%。考察了硝化剂、反应温度、反应时间等因素对硝化反应收率的影响,确定了最佳硝化反应条件：以硝硫混酸（体积比1：2）为硝化剂,反应温度为15~20℃,反应时间为1 h,硝化收率可达62.8%。A high safety synthesis method of 1,1-diamino-2, 2-dinitroethylene（FOX-7） was investigated. The 2-methoxy-2-methyl-4,5-imidazolidinedione was synthesized by cyclization reaction using acetamidine hydrochloride and diethyl oxalate as raw materials. The FOX-7 was obtained by the first step product nitrating with nitric-sulfuric mixed acid to 2-（dinitromethylene）-4,5-imidazolidinedione and then hydrolyzing. The overall yield is 56.7%. The influence of the factors including nitrating agent, reaction temperature, reaction time etc. on the yield of nitration reaction was investigated. The confirmed optimal nitration reaction conditions are as follows： nitric-sulfuric mixed acid（volume ratio 1：2） as nitrating agent, the reaction temperature 15~20 ℃, the reaction time 1 h. The nitration yield is 62.8%.
