Bis(2-fluoro-2,2-dinitroethoxy) 2,2,3,3,4,4,4- heptafluorobutoxymethane and a method of preparation

摘要

Bis(2-fluoro-2,2-dinitroethoxy) 2,2,3,3,4,4,4- heptafluorobutoxymethane, (HFBF), CF.sub.3 CF.sub.2 CF.sub.2 CH.sub.2 OCH OCH.sub.2 CF(NO.sub.2). sub.2 !.sub.2, is an energetic plasticizer with a melting point of -18. degree. C. and thermal stability up to 150 C. HFBF is miscible with polyfluoro- and polynitropolymers and useful as a plasticizer in plastic-bonded explosives.
