Abstract

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.

Claims (8)

1. A method comprising:

reacting at elevated temperature a suspension of diaminopicric acid in water and an aqueous alkyl hydroxide to form a reaction product; and

acidifying said reaction product to produce trinitrophloroglucinol.

2. A method comprising:

suspending diaminopicric acid and diammonium hydrogen phosphate in dry sulfolane;

heating the suspension with stirring;

cooling the suspension; and
