Using 3,3′-dicyanodifurazanyl ether (FOF-2) as starting materials, an excellent energetic plasticizer 3,3′-bis(fluorodinitromethyl) difurazanyl ether (FOF-13) was synthesized via a novel five-step synthetic method, and its structure was characterized by IR, ¹H NMR, ¹³C NMR, ¹⁹F NMR and elemental analysis. The main properties of FOF-13 are followed as: its density is 1.92 g·cm^-3, and melting point 43.5 ℃(DSC), impact sensitivity above 14 J, friction sensitivity 64%, and the mean detonation velocity is 8497 m·s (1.69 g·cm^-1). It shows that FOF-13 is a type of competitive energetic plasticizer.
