3, 3-Bis(difluoroaminomethyl)oxetane(BDFAO) is a new energetic compound. BDFAO was synthesized from 3, 3-bis(chloromethyl)oxetane(BCMO) by amination, esterification and fluorination. Total yield is about 43%. Synthesized compounds were characterized by IR, ¹H NMR, ¹³C NMR, GC (gas chromatograph) and elemental analysis. It was proved to be BDFAO and its purity is above 97%. The thermal properties of synthesized BDFAO were investigated by TG-DTA(thermogravimetry and differential thermalanalysis). Results show it has better thermal stability and its melting point is about 43.5 ℃. The sensitivities of BDFAO were determined by GJB772A-1997. The impact sensitivity H₅₀ is about 28.5 cm(5 kg hammer), the friction sensitivity is 100% (90° angle, 3.92 MPa) and it is insensitive to impact but sensitive to friction.
