Abstract
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
Claims12
A method to synthesize triaminotrinitrobenzene microparticles, comprising:
- providing a first solution comprising triaminotrinitrobenzene dissolved in an ionic liquid;
- providing a second solution comprising a nonionic surfactant and a solvent that is immiscible in and has a high polarity contrast against the ionic liquid;
- mixing the first and the second solutions while being sonicated to form an emulsion comprising micelles of the first solution dispersed in the solvent;
- and
- adding an anti-solvent precipitant to the emulsion to precipitate microparticles of triaminotrinitrobenzene in the micelles.
