Approaches to Synthesis of Caged Nitramine Explosives

Two of the most important military explosives are RDX (13.5-UinitH -U,5-hexahydrotriazine (3) and HMX (1) (Refs. 10-17). [Pg.97]

Both RDX and HMX are prepared by the first method. Reactant hexamethylenetetramine (hexamine, 4) may be directly nitrated with nitric add to produce a mixture of RDX and HMX (principally RDX) (Refe. 10,12). Another nitration procedure that employs nitric acid, ammonium nitrate, and acetic anhydride is used to prepare HMX (Refe. 11,17). [Pg.98]

The second approach to cyclic nitramines may be illustrated in the reaction of ethylenedinitramine (5) with formaldehyde to produce l,3-dinitro-l,3-diazacyclopentane (6) (Refe. 18-20). This approach has limitations when applied to more complex cyclic nitramines (Ref. 20). [Pg.98]

the preferred approach to caged nitramines is usually the fifit method, which departs from a caged polyamine containing the required number of amino groups in the desired positions. [Pg.99]
