A new type of flexible explosive(HFE) with high energy and low vulnerability based on H‐RDX(High‐quality RDX) was proposed. Fundamental characterizations of H‐RDX, including infrared testing and particle size measurement, were carried out. The technological parameters of the process were researched. Mechanical sensitivities were characterized by im...

Implementation of clean energy and renewables is essential for the consideration of environmental impact because it can be implemented in supply chain networks and sustainable management procedures for safety. In order to study the safety life failure criterion of a triple base propellant under the failure mode of mechanical properties, an accelera...

To study the relationship between the migration of desensitizer and combustion performance of a double-base propellant, the concentration distribution of desensitizer in aged samples was measured by micro-infrared spectroscopy, and the diffusion model was established. The combustion performance parameters were measured and calculated by closed bomb...

The extent of damage that is developed during the production, transportation, storage, and handling of propellants after a low-velocity impact is an important factor in evaluating a dangerous threat such as deflagration-to-detonation transition. In this paper, a friability test was performed to evaluate the critical impact ignition velocity ( CIIV)...

Ensuring adequate safety during the production, transportation and storage of ammonium nitrate (AN) has always been a matter of concern. In particular, the combustion and explosion of other chemicals in fire conditions could lead to secondary explosions of AN. An understanding of the effect of fire conditions on the blast characteristics of AN and...

In order to investigate and compare the effects of RDX crystal quality on the safety and mechanical properties of pressed PBX, different RDX-based PBXs were prepared by a water suspension granulation method. The surface morphology, thermal decomposition properties, impact sensitivity, and mechanical properties of high-quality RDX (H-RDX) and PBX we...

The hydroxyl-terminated polyether (HTPE) solid propellants are widely recognized as promising alternatives for hydroxyl-terminated polybutadiene (HTPB) propellants due to their compliance with insensitive munition characteristics of composite solid propellant. This study reports thermal stability investigation of HTPE solid propellants in different...

Tert‐butyl peroxypivalate is a typical free radical polymerization initiator due to the active O−O peroxide group, and it is a thermal instability material. To evaluate the thermal safety of tert‐butyl peroxypivalate, Dewar test, Differential Scanning Calorimetry (DSC) and Accelerating Rate Calorimeter (ARC) were used to study the self‐accelerating...

Aromatic para-functionalized NCN pincer compounds tethered to a triethoxysilane moiety through a carbamate linkage were immobilized on ordered MCM-41 molecular sieve using a grafting process. The acquired immobilized organometallic pincer complexes were synthesized in high yields with no complex degradation and characterized by IR sprctroscopy, ele...

Twelve OCO bisacetamide ligands 4aa-4dc were synthesized after condensation of isophenylenediamines 1a-1d and anhydride/acyl chlorides. The corresponding Pd(II)–OCO–H(5aa-5ac), Pd(II)–OCO–Me(5ba-5bc), Pd(II)–OCO–OMe(5ca-5 cc), Pd(II)–OCO–NO2(5da-5dc) pincer complexes were prepared via C-H activation of precursors and Pd(OAc)2, and characterized by...

Three benzenedicarboxamide ligands (L) were designed and synthesized, and each was used to prepare a palladium(II) complex Pd(L)Br and Pd(L)(OAc). These NCN pincer complexes were used to catalyze the α-arylations of a variety of ketones with aryl chlorides or bromides in various solvents, and moderate-to-excellent yields were obtained (up to 95%)....
Article
A new type of composite explosive used in a permissible detonator for coal mining has been manufactured through a two-phase granulation process. The new composite explosive (NCE) contains 79–88 wt% RDX, 3–5 wt% polymer binder, 1.5–2.5 wt% insensitive agent, 6–14 wt% sodium aluminum silicate (SAS), and 1–2 wt% polyvinyl alcohol (PVA). Firstly, a wat...

In 2015 a series of explosions occurred at a container storage station at the Port of Tianjin, China, on Wednesday, 12 August 2015, that killed over one hundred people and injured hundreds of firemen and others. The first two explosions happened within 30 seconds of each other at the facility. The second explosion was larger and involved the detona...

A novel hydrogen storage alloy was used in hexogen-based thermobaric explosive (RDX-based TBE). Two types of fashioned explosive charges with mass of 160 g and 500 g were used in this work. The energy of TBE was tested by underwater explosion. The results indicate hexogen-enriched novel hydrogen storage alloy can produce higher bubble energy than t...

... The thermal decomposition mechanism of AN subjected to heating has been extensively studied. 16,36,37 This situation, along with the absence of sufficient prevention resources, can lead to a mass explosion of the product, as occurred in the accident analyzed in this article. A violent shock from a projectile or sufficiently powerful pressure wave can also trigger the detonation of AN. 25 The accident happened when the lorry was overtaking another The accident caused two fatalities and injuries to five persons. ...
... Thus, if an explosive is unable to resist external mechanical stimuli, defects such as cracks may develop inside an explosive charge, probably resulting in the hot-spot initiation of such a heterogeneous explosive [7][8][9]. Therefore, chemical additives or binders are often incorporated into the formulation of an explosive to improve its mechanical properties [10][11][12]. ...
... Mikhaylov et al. have recently studied the fabrication of acyclic diaminocarbene Pd complexes supported on amino-functionalized polystyrene (ADC-PdII) and their stability and catalytic application in the SCR (Scheme 79) [98]. The two types of Pd(II)-diaminocarbenes complex studied had protons either at both nitrogen atoms (18) or at one nitrogen atom (19); catalyst (18) was catalytically shown to be more active than (19) because of the enhanced availability of active catalytic sites. Nevertheless, catalyst (19) showed high stability in the SCR. ...
... The scope of the a-arylation was investigated by varying ketone species under the same conditions, including both aryl and alkyl ketones with different substituent groups ( Table 5). The arylated products could be generated from bromobenzene with aryl ketones bearing electron-donating or electronwithdrawing substituents (6a-6p), and the yield were satisfactory compared with our previous work [49]. Then cyclohexanone was utilized as a substrate to explore the feasibility of aliphatic ketones under identical conditions. ...
... Results show that Al powders increase the combustion efficiency of B, and the metallized explosive (cyclotrimethylene-trinitramine (C 3 H 6 N 6 O 6 , RDX)/AP/metal powder/binder = 36/20/35/9) containing metal powders of Al/B = 90/10 has the highest bubble energy and total useful energy. Chen et al. [7] measured the underwater explosion parameters of metallized explosives (RDX/AP/metal powder/binder = 36/20/35/9) including a novel hydrogen storage alloy (Al/B/MgH 2 = 70/10/20) as the metal powders, results show that the RDX-based explosive enriched with the novel hydrogen storage alloy exhibits slightly higher bubble energy and total energy than https://doi.org/10.1016/j.combustflame.2020.07.045 0010-2180/© 2020 The Combustion Institute.
