A new method for the synthesis of industrially important azoimidazolium dyes is presented. The procedure is based on a reagent which is rarely used in the context of synthetic organic chemistry: nitrous oxide ("laughing gas"). N2O is first coupled to N-heterocyclic carbenes. Subsequent reaction with aromatic compounds through an AlCl3-induced C-H activation process provides azoimidazolium dyes ...

Inorganic electrolytes are assumed to significantly impact the flotation performance of graphite resources; however, underlying mechanism is still unclear. In this work, effect three inorganic salts, including KCl, MgCl2, and AlCl3, was studied on graphite. Flotation results indicated increased recovery with addition KCl regardless pulp pH. MgCl2 improved under acidic slightly alkaline conditio...

Due to TiAl alloys’ excellent properties, alloys have received widespread attention from researchers. However, the high energy consumption and lengthy process of traditional preparation methods always limited large-scale application alloys. This article develops a new method for preparing TiAl-based alloy powder via magnesium thermal reduction TiO2 in AlCl3-KCl molten salt. In this study, propo...

Reactive oxygen species (ROS) at high concentrations induce oxidative stress, an imbalanced redox state that is a prevalent cause of neurodegenerative disorders. This study aimed to investigate the protective effect Capsosiphon fulvescens (CF) extract on stress-induced impairment cognitive function in models diseases. CF was extracted with subcritical water and several solvents H2O2 (0.25 mM) o...

Magnetic seeding coagulation (MSC) process has been used to accelerate flocs sedimentation with an applied magnetic field, offering large handling capacity and low energy consumption. The interactions of three typical Al species, aluminum chloride (AlCl3), Al13O4(OH)247+ polymer (Al13), (AlO4)2Al28(OH)5618+ (Al30), particles (MPs) were examined clarify the MSC process. In traditional (TC) proce...

We have synthesized the novel 4-(4-hydroxy-benzyl)-3-phenyl-chromen-2-one which is a precursor of SERMs with a smaller number of steps and good yield. Two methodologies for the synthesis have been worked out. Anhydrous BF3·Et2O catalyzed reaction was found to be selective for product formation while anhydrous AlCl3, FeCl3, and SnCl4 catalyzed ones were nonselective.

At the core of aluminum (Al) ion battery is liquid electrolyte, which governs underlying chemistry. Optimizing rheological properties electrolyte critical to advance state art. In present work, chloroaluminate made by reacting AlCl3 with a recently reported acetamidinium chloride (Acet-Cl) salt in an effort make more performant electrolyte. Using AlCl3:Acet-Cl as model we build on our previous ...

A mechanochemical process for the synthesis of alane (AlH3) starting from lithium hydride (LiH) and aluminium chloride (AlCl3) at room temperature and the underlying reaction pathway have been studied. In contrast to a conventional process using the same two reactants dissolved in diethyl ether, our approach enables a solvent-free synthesis, thereby directly leading to adduct-free alane. The me...
