N2 - The explosive triacetone triperoxide (TATP) is produced by the
acid-catalyzed reaction of hydrogen peroxide and acetone, and methods
for its identification are important in forensic and military scenarios.
Previous work has documented concomitant crystalline polymorphism of the
crude reaction product. Here, we have investigated the crystalline
phases resulting from TATP syntheses from aqueous hydrogen peroxide as
well as from sodium percarbonate and urea peroxide as oxidant sources,
under different concentrations and types of acid. Powder X-ray
diffraction (PXRD) patterns of the as-prepared powders indicate that, in
contrast to previously published conditions, rapid precipitations afford
a pure crystalline phase of TATP. High concentrations of Bronsted acid
lead to the selective formation of a single kinetic crystalline phase,
while a Lewis acid (SnCl4) gives rise to a pure specimen of the
thermodynamic phase. Additionally, this study highlights the utility of
PXRD as a rapid and high
