3,3′-二(氟偕二硝基)二呋咱基醚(FOF-13)新法合成

Abstract

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, 1 H NMR, 13 C NMR, 19 F 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.
