Huang, Shiqi published the artcileSynthesis and combustion catalytic activity of ferrocene-based energetic compounds, Synthetic Route of 1455-77-2, the main research area is combustion catalytic activity ferrocene based energetic compound crystallog.

Ammonium perchlorate (AP) is a common oxidizer in composite solid rocket propellants due to its excellent burning characteristics, good processability, and storability. Owing to their outstanding catalytic effects, ferrocene, and its derivatives have become the most widely used burning rate catalysts (BRCs). The addition of ferrocene and its derivatives to AP rendered performance optimization. In this study, azole-based ferrocenyl compounds were successfully synthesized. The compounds were characterized by single-crystal X-ray diffraction, UV-vis spectroscopy, and other techniques. The thermal degradation of AP catalyzed by these compounds was evaluated by differential scanning calorimetry and thermogravimetric anal. Results revealed that the decomposition peak temperature of AP dramatically decreases and that the released heat of AP significantly increases with the new compounds as additives. Hence, the six azole-based ferrocenyl BR catalysts are favorable for the combustion catalytic activity.

Yang, Ximei published the artcileFurther study on energetic salts of TNATT anion, Synthetic Route of 1455-77-2, the main research area is energetic salt nitroamino functionalized fused triazole synthesis.

Six energetic salts based on fully nitroamino-functionalized fused-triazole were synthesized. All salts were characterized by IR, multinuclear NMR spectroscopy, thermal anal., and elemental anal. The crystal structures of the salts 2, 3, and 6 were confirmed by single-crystal X-ray diffraction. The densities of all salts lie in the range between 1.77-1.83 g cm-3, while their decomposition temperatures range within 142-200°. Most energetic salts are slightly more sensitive than RDX. The calculated detonation pressures and velocities (Gaussian 09 and EXPLO5) of salts 2-7 range within 21.7-39.3 Gpa and 7867-9401 m s-1, resp. Salt 7 exhibits a high d. (1.83 g cm-3), acceptable thermal stability (Td = 179°) and sensitivity (IS = 7 J, FS = 216 N), and excellent detonation performance (vD = 9401 m s-1, P = 39.3 GPa), which suggest that salt 7 may well have promising applications as high-energy-d. materials.

In this paper, the interface polymerization method was used to prepare Osmanthus essential oil microcapsules. The optimal preparation process of Osmanthus essential oil microcapsules was explored as follows: the dosage ratio of Osmanthus essential oil to N100 was 6:1, the reaction temperature was 70°C, and the reaction time was 2 h. The encapsulation efficiency of Osmanthus essential oil microcapsules could reach 80.31%. The particle size distribution, morphol., chem. structure, and thermal stability of the obtained microcapsules were characterized by laser particle size analyzer, SEM, Fourier transform IR spectroscopy, and thermogravimetric anal. The release kinetics and storage stability experiments of the microcapsules were studied. The results showed that the average volume diameter of the microcapsules was 101.2 μm. The microcapsules were in the shape of full spheres, with a smooth surface, low viscosity, and high elasticity. Microencapsulation improved the thermal stability of Osmanthus essential oil and promoted the slow release of essential oil. The synthesized microcapsules showed good storage stability under refrigerated and dark conditions, which indicated that microcapsules had broad application prospects in food, medicine, and other fields. Practical Application : In this study, we prepared a polyurea membrane to encapsulate Osmanthus essential oil microcapsules by interfacial polymerization The encapsulation conditions of the microcapsules were optimized and the structure of the microcapsules was characterized in this study. The results showed that microcapsules had a full spherical shape with a smooth surface, high elasticity, good sustained-release ability, good thermal stability, and storage stability.

Xu, Jian-Gang published the artcileEnergetic azide-based coordination polymers: Sensitivity tuning through diverse structural motifs, Synthetic Route of 1455-77-2, the main research area is energetic azide based coordination polymer structural analysis sensitivity.

Energetic coordination polymers (ECPs), as a new class of energetic materials (EMs), have attracted extensive attention in recent years. However, controllable modulation of mech. sensitivities and the establishment of structure-function theor. models of ECPs to meet different applications remain great challenges. Herein, we designed and synthesized four azide-based ECPs, [Cd2(N3)2(datz)2]n 1 (Hdatz = 3,5-diamino-1,2,4-triazole), [Cd(N3)2(brt)2]n 2 (brt = 4,4â€?bi-1,2,4-triazole), [Cd(N3)2(btzp)]n 3 (btzp = 1,3-di(tetrazol-1-yl)propane), and [Cd2(N3)4(btzb)]n 4 (btzb = 1,4-bis(tetrazol-1-yl)butane). Because of the existence of consolidated network structures, high-energy linkers, and diverse structural motifs, compounds 1-4 exhibit reliable thermal stabilities, tunable mech. sensitivities, and considerable heats of detonation (ΔHdet) with the ΔHdet values of 3.390, 3.412, 3.947 and 4.504 kJ·g-1, resp., which are two times higher than those of com. LA (lead azide) and the reported AgMtta (AgMtta = [Ag(Mtta)]n, HMtta = 5-methyl-1H-tetrazole). The sensitivity measurements demonstrate that the sensitivity toward impact of 1-4 displays in the following order: 1 (>40 J) â‰?2 (8 J) < 3 (2.5 J) < 4 (2 J). In particular, compound 1 features scarce insensitivity compared with sensitive 2, 3, 4 and most of known azide-based EMs. Furthermore, theor. calculations, structural analyses, and exptl. results revealed that the different sensitivities of the four ECPs are mainly dependent on two different structure models for the first time. The insensitive 1 is ""body frame structure"" model, while the sensitive 2-4 belong to ""non-body frame structure"" model. Our study enlightens new insights into structures behind mech. sensitivities for optimizing advanced EMs. Chemical Engineering Journal (Amsterdam, Netherlands) published new progress about Explosives. 1455-77-2 belongs to class isoquinoline, name is 3,5-Diamino-1,2,4-triazole, and the molecular formula is C2H5N5, Synthetic Route of 1455-77-2.

Chen, Dongxu published the artcileIntroduction of the acylamino group to bridged bis(nitroamino-1,2,4-triazole): a strategy for tuning the sensitivity of energetic materials, Formula: C2H5N5, the main research area is energetic material nitroaminotriazole acylamino introduction sensitivity tuning.

In this work, the acylamino group has been introduced into energetic materials to build acylamino-bridged bis(1,2,4-triazole) 3 and its nitration derivative 4. Both 3 and 4 were thoroughly characterized via spectroscopic and structural methods. In addition, their sensitivities toward friction and impact were determined and the energetic performances of 3 and 4 were calculated using the EXPLO5 code. Compound 3 is insensitive to mech. stimulation (IS: 40 J, FS: 320 N). Besides, compared with the C-C-bonded compound DNABT (IS: 3 J, D: 8355 m s-1) without any bridging group, 4 achieves a balance between the sensitivity (IS: 18 J, FS: 200 N) and the detonation velocity (D: 8564 m s-1). The effect of introducing an acylamino group into 3 and 4 was elucidated using HOM: O-LUMO anal. and the anisotropy of the induced current-d. method.

Jiang, Haihua published the artcileVapor-Liquid Phase Equilibrium for Separation of Isopropanol from Its Aqueous Solution by Choline Chloride-Based Deep Eutectic Solvent Selected by COSMO-SAC Model, Quality Control of 598-50-5, the main research area is vapor liquid phase equilibrium separation isopropanol aqueous solution; choline chloride deep eutectic solvent COSMO SAC model.

To sep. isopropanol from its aqueous solution by distillation, the deep eutectic solvents (DESs) with choline chloride, which were screened using the COSMO-SAC mode, were applied to eliminate the azeotropic point. The charge d. distribution over the mol. surface was calculated for isopropanol, water, and DESs to analyze the interactions between different species. Based on the screening results, a DES consisting of choline chloride and triethylene glycol in a molar ratio of 1:3 was selected. To validate the selected DES for the separation of isopropanol from its aqueous solution, the isobaric vapor-liquid equilibrium (VLE) data for the system of isopropanol + water + DES were measured at a pressure of 101.3 kPa. According to the measured VLE data, the azeotropic point of isopropanol and water can be eliminated by the DES at a concentration of 10 wt %. Meanwhile, the thermodn. consistency of the VLE data was checked by the van Ness test. The non-random two-liquid model was employed to correlate the VLE data, which were in agreement with the measured VLE data.

Gao, Tong published the artcileMechanochemical synthesis of three-component metal-organic frameworks for large scale production, Category: isoquinoline, the main research area is zinc amino triazolate isophthalate MOF mechanochem preparation gas adsorption; XPS zinc amino triazolate isophthalate MOF.

Two pillared-layer metal-organic frameworks with pcu network were synthesized by the mechanochem. reaction of three components (ZnO, 3-amino-1,2,4-triazole (Hatz) or 3,5-diamino-1,2,4-triazole (Hdatz), and isophthalic acid (H2ipa)) at room temperature with space-time yield up to 4800 kgm-3 day-1. The mechanochem.-synthesized [Zn2(atz)2(ipa)] (Zn-atz-ipa) and [Zn2(datz)2(ipa)] (Zn-datz-ipa) exhibit the high purity and porosity with BET surface areas of 655 and 572 m2g-1, resp., which are comparable with those synthesized by the traditional solvothermal method. In C2H4/C2H6 (volume/volume = 1/1) breakthrough experiment, Zn-datz-ipa can preferentially adsorb C2H6 over C2H4, showing a great potential for one-step purification of C2H4. In addition, this mechanochem. method can be scaled up to 100 mmol magnitude with single-pass production up to 20.0 g.
