A novel method used to synthesize diacetone diperoxide (DADP) from acetone and hydrogen peroxide without the presence of a catalytic agent is presented. Previously reported syntheses used toluenesulfonic and m‐sulfonic acid as catalyst. DADP was prepared with a purity of 99.99 %. The melting point range (128.5–134.5 °C) is consistent with reported values. The success of the reported procedure depends on controlling the ratio between acetone and hydrogen peroxide as well as the temperature of the reaction mixture. The purified crystalline DADP samples were characterized using NMR, Raman, and IR spectroscopy, differential scanning calorimetry, gas chromatography and open atmosphere chemical ionization mass spectrometry (DART™). The structure was compared to the well‐known cyclic trimer triacetone triperoxide (TATP). The proposed synthetic scheme can be useful for preparing small amounts of the cyclic organic peroxide for characterization and fundamental studies and for formulation of gas chromatography, high performance liquid chromatography, and mass spectrometry standards.

We report the preparation of explosives nanoparticles of RDX and TNT in a variety of substrates that include glass, silicon and stainless steel. The explosive nanoparticles were prepared by means of pneumatically assisted nebulization (PAN) using an electrospray (ESI) needle, which allowed for the direct deposit of the energetic material onto the substrate. The deposited nanoparticles were characterized by optical microscopy, Scanning Electron Microscopy (SEM), Energy Dispersive X-ray analysis (EDX) and Raman Microscopy. SEM micrographs showed that the process produced particles with a mean size in the range of 80 -500 nm and a narrow size distribution. For TNT, the process produced smaller particles with a narrower size distribution. The EDX spectrum showed the presence of carbon, nitrogen and oxygen consistent with the elemental composition of the energetic materials. The chemical properties of the nanoparticles were also determined by vibrational spectroscopy.
