Latest Patents

One of his latest patents involves the synthesis and purification of 1,3,5-triamino-2,4,6-trinitrobenzene (TATB). This method describes a process to convert surplus nitroarene explosives, such as picric acid and ammonium picrate, into TATB. The process comprises three major steps: the conversion of picric acid/ammonium picrate into picramide, the conversion of picramide to TATB through vicarious nucleophilic substitution (VNS) of hydrogen chemistry, and the purification of TATB. Another significant patent details the synthesis of trinitrophloroglucinol and triaminotrinitrobenzene (TATB). This method describes the direct amination of picric acid to diaminopicric acid, which is then converted to trinitrophloroglucinol and triaminotrinitrobenzene.
