The TATP prepared in the presence of catalysts such as methanesulfonic, perchloric, or sulfuric acid, has been found to undergo spontaneous transformation to DADP. This transformation, however, does not occur if TATP is purified or prepared using hydrochloric acid. Using nitric acid or tin(IV) chloride for catalysis results in TATP that transforms to DADP only to a small extent (max. 1%). The rate of transformation depends on the storage temperature and on the molar ratio of catalyst to acetone ( n c /n a ) used during the preparation of TATP. The faster rate of the transformation was observed at high temperatures and higher molar ratio n c /n a .
