Methods of producing 1,3,5-triamino-2,4,6-trinitrobenzene (TATB), from alkoxy derivatives of phloroglucinol, such as 5-methoxyresorcinol, 3,5-dimethoxyphenol, or 1,3,5-trimethoxybenzene, are disclosed. The alkoxy derivatives may be exposed to and directly nitrated with a reaction mixture comprising a sulfuric acid solution and at least one nitrate salt. The nitrated alkoxy derivative of phloroglucinol may be alkoxylated and, thereafter, aminated to produce the TATB.

Conditions for the mild and efficient nitration of phloroglucinol (1,3,5-trihydroxybenzene), 5-methoxyresorcinol,3,5-dimethoxyphenol, and 1,3,5-trimethoxybenzene have been developed. Yields of the trinitro derivatives are excellent (similar to 90%) for systems having one or more hydroxyl groups, and in the case of 1,3,5-trimethoxybenzene, the trinitro analog was obtained in 62% yield. The optimum nitration conditions utilize sulfuric acid (94-98%) and an inorganic nitrate salt.
