3.5- Difluor-2,6-dinitro

Dinitro-l,3-difluorohenzene (DNDFB) or 2,4-Dinitro-l-difluorobenzene (DNFFB) (called 4.6-Difluor-1.3-dinitro-benzol in Ger), prisms (from ale), mp 73-75° readily sol in hot ale less sol in cold ale can be prepd by nitrating either 1,3-difluorobenzene or 1-nitr o-2,4-di fluoro benzene with mixed acids (Ref 1) or by other methods (See Refs)...
