4,6-Dinitrobenzofuroxan, an Important Explosive Intermediate.

摘要

The preparation of 4,6-dinitrobenzofuroxan (DNBF) from either benzofuroxan or picryl chloride is described. Batches of up to 20 g have been obtained in suitable crystalline from via recrystallization from a number of solvents. DNBF exhibits impact and electrostatic sensitivity characteristic of a sensitive secondary, such as RDX, and should be handled accordingly. Ignition of small samples (< less than 200 mg) results only in deflagration; detonation can be achieved by the strong shock from detonating lead azide but power output appears to be significantly lower than RDX.
