Study of TATP: Stability of TATP solutions

Popis výsledku v původním jazyce

Stability of raw TATP (3,3,6,6,9,9-hexamethyl-1,2,4,5,7,8-hexoxonane) samples in solutions of common solvents was studied to highlight problems faced by forensic labs in identification and analysis of organic peroxide samples. The TATP samples were prepared by reaction of acetone and hydrogen peroxide (30%) with the aid of following catalysts: hydrochloric, sulfuric, nitric, perchloric and methanesulfonic acid. Acetone, acetonitrile, methanol and acetonitrile/water solutions of TATP samples were prepared and stored at 50 8C. Various degrees of stability were observed for particular combination of catalyst and solvent ranging from totally unstable (catalyst-H2SO4/any solvent) to very stable (catalyst-HCl/solvent acetonitrile). Purification of crude TATPby re-crystallization results in product stable in all investigated solvents. Stability of solution prepared from re-crystallized DADP (3,3,6,6-tetramethyl-1,2,4,5- tetroxane) was found to be on the same level as the stability of solutio
