A method to convert surplus nitroarene explosives into trinitrophloroglucinol and triaminotrinitrobenzene (TATB) is described. Picric acid is directly aminated to diaminopicric acid, which is converted to trinitrophloroglucinol and triaminotrinitrobenzene.

A method to convert surplus nitroarene explosives (picric acid, ammonium picrate,) into TATB is described. The process comprises three major steps: conversion of picric acid / ammonium picrate into picramide; conversion of picramide to TATB through vicarious nucleophilic substitution (VNS) of hydrogen chemistry; and purification of TATB.

Methods of producing TATB are disclosed. The method comprises providing acid wet TNPG and distilling water from the acid wet TNPG. The TNPG is reacted with an alkoxylating agent to form a solution of 1,3,5-trialkoxy-2,4,6-trinitrobenzene solution, which is reacted with an aminating agent. An alternate method comprises nitrating phloroglucinol in a first vessel to produce TNPG, which is reacted with an alkoxylating agent in a second vessel to form a solution comprising 1,3,5-trialkoxy-2,4,6-trinitrobenzene and at least one of at least one volatile byproduct and at least one nonvolatile byproduct. The at least one of at least one volatile byproduct and at least one nonvolatile byproduct is removed in situ. The 1,3,5-trialkoxy-2,4,6-trinitrobenzene is reacted with an aminating agent.

A new, rapid and inexpensive synthesis method for monodispersed triaminotrinitrobenzene (TATB) microparticles based on micelle-confined precipitation that enables control of microscopic morphology. The morphology of the TATB microparticles can be tuned between quasi-spherical and faceted by controlling the speed of recrystallization. The method enables improved performance and production consistency of TATB explosives for military grade explosives and propellants
