Pikrylaminodinitropyridin (PYX) is an energetic aromatic nitro compound, which is used for the production of particularly heatproof explosives for the oil exploration.
PYX is innocuous and not strike-attractive. It has the best temperature stability (1 hr. with 270"°C, 100 hr. with 250"°C) of all well-known high-explosive explosives, is however somewhat less explosive than Hexanitrostilben.
From heating up 2,6-Diaminopyridin [2,6-Bis (pikrylamino) results to 141-86-6] C5H7N3 and Pikrylchlorid [88-88-0] in water-free ethanol with Natriumhydrogencarbonat pyridin (BPAP) in 87% yield, from which by nitrating with Hoko nitric acid (>95%) (5 hr., return flow) PYX in 82% yield is received.
PYX results in form of needle-shaped crystals, which are loosened in Dimethylsulfoxid (DMSO). PYX in form of pure cubic crystals is again separated by addition of acetone and water for solution.
PYX serves high pressures to 150 MPa for the production of hollows charge for the employment with high ambient temperatures to 260 "°C and. It is used in large quantities with the exploitation by
