Investigating the thermal decomposition and detonation mechanisms of DNAN by combining TG-FTIR-MS with DFT ReaxFF MD.
The Pearl River Estuary (PRE) on the east coast of Guangdong Province in South China is a complicated hydrodynamic system affected by various forcing functions including tides, wind forcing, and sea surface heat freshwater fluxes. PRE also receives large amount runoff from through eight major river inlets. In this study, three-dimensional circulation, hydrography, associated temporal variability adjacent coastal waters during dry season December to March are examined using triple-nested...
A new high-energetic and insensitive melt-cast material was synthesized, its polycrystalline properties were characterized theoretically investigated.
The hydroxyl-terminated polyether (HTPE) solid propellants are widely recognized as promising alternatives for polybutadiene (HTPB) due to their compliance with insensitive munition characteristics of composite propellant. This study reports thermal stability investigation HTPE in different scales the help differential scanning calorimetry (DSC, 0.9 mg), accelerating rate (ARC, 0.219 g), and slow cook-off (112 g) tests by taking HTPE/A3/Al/AP/PSAN propellant an example. More importantly,...
In order to investigate and compare the effects of RDX crystal quality on safety mechanical properties pressed PBX, different RDX-based PBXs were prepared by a water suspension granulation method. The surface morphology, thermal decomposition properties, impact sensitivity, high-quality (H-RDX) PBX characterized SEM, optical microscope, DSC, sensitivity tester, universal material testing machines. results have shown that H-RDX has smoother surface, regular shape, higher density, fewer...
Numerous accidents of emulsion explosive (EE) are attributed to uncontrolled thermal decomposition ammonium nitrate (ANE, the intermediate EE) and EE in large scale. In order study characteristics ANE different scales, a large-scale test modified vented pipe (MVPT), two laboratory-scale tests differential scanning calorimeter (DSC) accelerating rate (ARC) were applied present study. The scale effect water both play an important role stability EE. measured temperatures MVPT 146°C 144°C,...
Claisen–Schmidt condensation of 2′-hydroxyacetophenone with benzaldehyde using easily recovered and efficiently reused ionic liquids (ILs) results 2′-hydroxychalcone in 89% yield under ultrasound irradiation. Compared to classical methods, the advantages this method are mild conditions, shorter reaction time, high yield. This ''green'' has been applied synthesis several substituted 2′-hydroxychalcones achieving, all cases, excellent activities selectivities.
A novel hydrogen storage alloy was used in hexogen-based thermobaric explosive (RDX-based TBE). Two types of fashioned charges with mass 160 g and 500 were this work. The energy TBE tested by underwater explosion. results indicate hexogen-enriched can produce higher bubble than that enriched aluminum. total useful 4.7 % (160 g) 6.4 (500 an the same aluminum content, Trotyl (TNT) equivalent 2.1 times. heat explosion test shows similar result improve energy, about 7.9 aluminized.
An energetic plasticizer MN reinforced MEC with superior mechanical performance was fabricated and the reinforcement mechanism investigated by microscopy QC/MD method.
Abstract 5,6‐di(2‐fluoro‐2,2,–dinitroethoxy)‐2,3‐dicyanopyrazine was synthesized in a one‐pot process starting from 5,6‐dichloro‐2,3‐dicyanopyrazine. Its structure fully characterized by 1 H, 13 C, 15 N and 19 F NMR, mass spectroscopy, infrared spectrum as well elementary analysis. Low‐temperature X‐ray diffraction employed for analyzing its crystal structure. It exhibits excellent thermal stability (onset m.p. 203 o onset dec. 222 C) which is comparable to those of...
Abstract Diaminoguanidinium N,N′ ‐dinitro‐ ‐bis(3‐dinitromethyl‐furazanate‐4‐yl)methylenediamine ( 5 ), a new melt‐cast energetic salt, was designed and synthesized via metathesis reaction from dipotassium 4 ) by using condensation of 3‐amino‐4‐chloroximinofurazan 1 followed mixture fuming nitric acid trifluoroacetic anhydride then KI reduction. The target products were thoroughly characterized NMR spectroscopy, vibrational spectroscopy (IR), elementary analysis, differential scanning...
