Abstract

Perchloric acid-triethylenediamine ammonium (DAP-4) was synthesized using triethylenediamine, ammonium perchlorate and perchloric acid as raw materials and its structure was characterized by elemental analysis, scanning electron microscopy and X-ray diffraction. The physical properties, thermal properties, sensitivity performance, stability, heat of explosion, specific volume, detonation performance and compatibility were tested and evaluated using DSC, TG, etc. The results showed that the density of DAP-4 was 1.839g/cm³, and the crystal density was 1.923g/cm³. DAP-4 had good hygroscopicity and heat resistance as well as qualified vacuum stability. Its impact sensitivity, friction sensitivity, flame sensitivity and hot wire sensitivity were 21.5cm, 56%, 7.8cm and 527.0mA, respectively, and it did not ignite due to static electricity, indicating good safety. The heat of explosion was 6194J/g, and 250mg DAP-4 could initiate RDX. DAP-4 was compatible with TNT, PYX, KClO4 and XM-19 nickel-based alloys, and was incompatible with RDX, HNS, T10 steel, 0Cr18Ni9 stainless steel, B19M white copper, 5A02 aluminum, 2A12-T4 aluminum, brass, and iron nickel cobalt glass sealing alloys.
