FOX-7 (1,1-diamino-2,2-dinitroethylene) was synthesized starting from the raw material 2-methylpyrimidine-4,6-dione after nitration and hydrolyzation. The title compound was characterized by means of IR, MS, NMR spectra and elemental analysis. The main factors which affected the yield were analyzed. The single crystals of the product were obtained from recrystalization. The CAD4 Diffractometer was used to measure the unit cell parameters of its single crystal. The sensitivities of electrospark and impact for FOX-7 were studied and compared with that of RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine), HMX (cyclotetramethylene tetranitramine) and TATB (triaminotrinitrobenzene). The results shows that the sensi-tivity of FOX-7 is lower than that of RDX, but higher than that of TATB. Compared with the recrystalized product, it is found that the surface topography and thermal properties of the raw FOX-7 have great effects on its properties. In this way, it can be improved and optimized.
