1, 1-Bis(picrylamino)-2, 2-dinitroethylene (TFT) was synthesized using 2, 4, 6-trinitrochlorobenzene and 1, 1-diamino-2, 2-dinitroethylene (FOX-7) as raw materials and KF and imidazole as catalysts by condensation with the yield of 71.3% and melting point of 225-226 ℃. Its structure was identified by IR, NMR and MS. Its thermal stability was analyzed by DSC and the decomposition temperature was 331.3 ℃, which indicating that its thermal stability was better than that of FOX-7. The theoretical density of TFT after optimizing predicted by Monte-Carlo method is 1.85 g·cm^-3. The heat of detonation, detonation velocity and detonation pressure predicted by Kamlet-Jacobs formula are 1751.26 J·g^-1, 8.83 km·s^-1 and 36.25 GPa, respectively. Impact sensitivity(H₅₀) is 156 cm. All the results show that TFT is more insensitive and has higher detonation pressure than FOX-7.
