PART 69 JF International Journal of Energetic Materials and Chemical Propulsion JO IJEMCP YR 2010 FD 2012-01-05 VO 9 IS 6 SP 549 OP 560 K1 ammonium perchlorate (AP) K1 HMTA K1 kinetics K1 isothermal TG K1 X-ray chrystallography K1 protonated hexamethylenetetramine perchlorate AB When hexamethylenetetramine (HMTA) was treated with cupric perchlorate at room temperature, protonation at one of the N atoms, it yielded protonated HMTA perchlorate (PHMTAP), C6H13ClN4O4 . It crystallizes in a monoclinic crystal system with the P21/n space group. On the other hand, when HMTA was treated with 20% perchloric acid in the absence of cupric perchlorate, the resulting product was ammonium perchlorate (AP), which crystallizes in an orthorhombic crystal system with the Pnma space group. Both PHMTAP and AP have been characterized by X-ray crystallography using a Nonius Kappa charge coupled device diffractometer. Thermolysis has been carried out by thermogravimetric, differential thermal analysis, ignition/explosion delay, and burning-rate measurements. The results have shown that PHMTAP salt was thermally less stable than AP. PB Begell House LK https://www.dl.begellhouse.com/journals/17bbb47e377ce023,4d2b6557160a173a,631e5b0100871e88.html
