Lewis hard acid AlCl 3 was softened by some butyl halides forming highly polarized liquids. These liquids are similar to the ionic liquids (ILs) with metallic complex anion and varying composition, and thus termed here as carbonium pseudo ILs (CPILs). The CPILs, that is, t -C 4 H 9 Cl-AlCl 3 , n -C 4 H 9 Cl-AlCl 3 , and t -C 4 H 9 Br-AlCl 3 , show very strong desulfurization activity for various thiophenic compounds like 3-methylthiophene, benzothiophene, and dibenzothiophene. The above thiophenic compounds can be removed completely from model oils within 20 min by a very small amount of CPILs reactive extractant. The extractive mechanism is deemed as an acid–base complexation along with alkylation of the thiophenic compounds, and the Lewis acidity comes from both carbonium ion (borderline acid) and the dissolved AlCl 3 (hard acid). The t -C 4 H 9 Cl-AlCl 3 shows good selectivity for three thiophenic compounds even in toluene-containing system. Further, some CPILs show satisfactory desulfurization performance for the model gasoline that mimics the composition of real one. © 2012 American Institute of Chemical Engineers AIChE J, 59: 948–958, 2013

The characteristics of the reaction for the preparation of dichlorophenylphosphine (DCPP) via benzene and PCl 3 in the presence of AlCl 3 were studied. Some unique characteristics were observed when a catalytic amount of AlCl 3 was used. Namely, more than one mole of DCPP was obtained per mole AlCl 3 , the reaction solution was layered, and DCPP could be directly separated. Our mechanistic study showed that benzene reacted with PCl 3 to form DCPP-AlCl 3 , and DCPP-AlCl 3 dissociated into DCPP and AlCl 3 , continuing to catalyze this reaction. This resulted in the high catalytic efficiency of AlCl 3 . The layering of the reaction solution was caused by the immiscibility of DCPP-AlCl 3 with the raw materials, greatly facilitating the dissociation process of DCPP-AlCl 3 . The formation of diphenylphosphorus chloride (DPC) was due to a continuous Friedel-Crafts reaction between DCPP and benzene. DPC cooperated with AlCl 3 to form the stable coordination compound DPC-AlCl 3 that did not dissociate and was responsible for the deactivation of AlCl 3 .

The density, viscosity and electrical conductivity of AlCl 3 -amide (amide = urea, acetamide , propionamide , butyramide) ionic liquid (IL) analogues with varied molar fractions of AlCl 3 were measured at temperatures ranging from 313 K to 373 K. All the experimental values were fitted with the empirical equations. Meanwhile, the molar volume and molar conductivity of AlCl 3 -amide were also obtained. Based on the results, the difference in the properties of AlCl 3 -amide IL analogues are mainly attributed to the species of amide ligands, which have significant effects on complex structure, ionic interaction and hydrogen bonding of IL analogues.

Piperidinium-based ionic liquids (ILs) were synthesized under mild conditions by coordinating N -alkyl- N -methylpiperidinium bromide ([Pip 1,x ]Br) with anhydrous AlCl 3 . The weak basicity of N -methylpiperidine had little impact on downstream problems from proton impurities and catalyst poisoning. The results of Fourier transform infrared (FT-IR), electrospray ionization mass spectrometry (ESI-MS), and nuclear magnetic resonance ( 27 Al NMR) confirmed that the active components in [Pip 1,x ]Br-2AlCl 3 ( χ = 0.67) were [Al 3 Cl 9 Br] − and [Al 2 Cl 6 Br] − . Besides, the reaction performance of [Pip 1,8 ]Br-2AlCl 3 under different conditions was carried out by single-factor experiment and further confirmed by orthogonal experimental method. Among these reaction conditions, the optimal combination was the reaction temperature of 40°C, ILs/O molar ratio of 0.2:1, px/O molar ratio of 12:1, and the reaction time of 30 min. Furthermore, [Pip 1,8 ]Br-2AlCl 3 had excellent stability and can be recycled 14 times. It was the high-efficiency catalytic activity and prominent recyclability that made continuous industrial production possible.

AlCl3-mediated protodeboronation of arylboronic acids and esters is reported herein. This method features mild reaction conditions, high reaction yields, as well as short reaction times. Mechanistic studies based on 11B NMR spectroscopy suggest that it might proceed through initial boron activation by coordination of AlCl3 to the oxygen atom of arylboronic acid or ester groups.

Aluminum chloride (AlCl 3 ) is an effective chlorinating agent and catalyst for the chlorination of low-grade titanium slag to produce titanium tetrachloride in molten salts. In this paper, the chlorination behavior of low-grade titanium slag by anhydrous AlCl 3 in AlCl 3 -NaCl molten salt was investigated. Thermodynamic analysis revealed that aluminum chloride can be an effective agent for low-grade titanium slag, and that the addition of NaCl can form a compound molten salt together with AlCl 3 to prevent the evaporation of AlCl 3 .chlorination experiments were conducted on low-grade titanium slag in AlCl 3 -NaCl molten salt to investigate the effects of temperature and the amounts of aluminum chloride and sodium chloride added. Under optimized experimental conditions, the selective separation of titanium from the titanium slag was effectively achieved, and the extraction rate of titanium reached 79.6%. Other impurity elements in the form of oxides or chlorides remained in the residue. Finally, a reaction mechanism for the extraction of titanium from low-grade titanium slag in AlCl 3 -NaCl molten salt has been proposed.

The electrochemical Al metal extraction in the room-temperature electrolyte is considered a green and sustainable approach, where temperature serves as a critical parameter that significantly influences the process. This study systematically investigates effects of the temperature on the thermal behavior of AlCl 3 - N -methylformamide (NMF) system and corresponding electrochemical process. Firstly, the thermogravimetric analysis and the in-situ temperature-rising Raman spectroscopy are combined to reveal the thermal behavior of AlCl 3 -NMF system. The results show that AlCl 2 NMF 2 + fractures to produce NMF and AlCl 3 at 360 K, while NMF decomposes at 360 K and AlCl 3 volatilizes at 440 K. Secondly, cyclic voltammetry and chronoamperometry illustrate that increasing temperature enhances the limiting diffusion current density of Al(III) and reduces the electro-crystallization nucleation induction time. Thirdly, XRD, SEM and non-contact optical microscope analyses indicate that the crystal orientation, the grain size, the micro-morphology, the surface roughness and the thickness of Al coatings electrodeposited in AlCl 3 -NMF system change with the rising temperature. The changes are related to the competition for the nucleation-growth of Al grains and the thermal stability of AlCl 3 -NMF system. Al coatings electrodeposited at 333 K possess the grain size of 24.8 nm, the thickness of 12.6 ± 0.5 μm and the absolute value of average roughness of 6.1 μm.

Conventional recycling of polyolefins and rubbers is hindered by high energy consumption, complex processing, and limited substrate compatibility—fundamental barriers that have long impeded practical waste valorization. Here, we overcome these limitations with a mechanochemical strategy that leverages AlCl 3 , a classic Lewis acid historically central to petroleum cracking, to catalytically degrade these recalcitrant polymers under ambient, solvent-free conditions. The process achieves near-quantitative conversion of polyethylene (>99%) and polypropylene (97%) within 30 minutes, yielding liquid hydrocarbons with exceptionally narrow carbon number distributions (C 8 –C 14 ) and polydispersity indices as low as 1.14—highly competitive uniformity for waste-derived oils. This efficiency extends readily to butadiene rubber and ethylene-propylene copolymer, and the catalyst maintains high activity during 11 successive feeding experiments, effectively processing real-world post-consumer waste with minimal pretreatment. Combining model-substrate experiments, selective poisoning studies, and DFT calculations, we propose a carbocationic pathway initiated by in situ Brønsted acid formation, involving selective C–C bond scission and intramolecular cyclization/aromatization. This work establishes a scalable, energy-efficient route that transforms plastic waste into high-quality hydrocarbon feedstocks, offering a transformative alternative to energy-intensive conventional methods.

The liver, a critical metabolic organ, is particularly vulnerable to damage upon aluminum exposure. However, the precise molecular mechanisms through which aluminum induces hepatotoxicity remain to be fully elucidated. This study aimed to investigate the adverse effects of aluminum exposure on mouse liver tissue. The results indicated that AlCl 3 exposure induced significant liver dysfunction, characterized by reduced adenosine triphosphate levels, elevated plasma alanine aminotransferase and aspartate aminotransferase. Histopathological analysis of liver tissue revealed marked histological damage, accompanied by substantial iron deposition. Further examinations demonstrated elevated hepatic levels of malondialdehyde, 4-hydroxynonenal, and reactive oxygen species, decreased levels of glutathione (GSH) and superoxide dismutase, increased levels of Oxidized glutathione (GSSG), and a reduced GSH/GSSG ratio. The mRNA and protein expression of ferroptosis-related molecules, including downregulated glutathione peroxidase 4 and solute carrier family 7 member 11, were significantly downregulated, while acyl-CoA synthetase long-chain family member 4, ferritin heavy chain 1, and iron regulatory protein 1 levels were significantly upregulated. Treatment with Ferrostatin-1 markedly ameliorated liver dysfunction and histopathological damage, attenuating signs of ferroptosis. These findings highlight the potential of ferroptosis-targeted therapies as a viable treatment strategy for aluminum exposure-induced hepatocyte injury.

Electrodepositing Al coatings on W 90 Cu 10 foils in AlCl 3 + LiAlH 4 Tetrahydrofuran–benzene electrolyte was reported in this work. Effects of variations in molar ratios of AlCl 3 /LiAlH 4 , current density and plating time on surface morphology and crystal orientations were studied, and the optimal values of three parameters were preliminarily gained. Results showed that Al coatings displayed dense and cone-shaped micro-crystallites, and the particle size of coatings increased obviously with increasing current density or decreasing the proportion of AlCl 3 . It was indicated that all of the electrodeposits exhibited a strong preferred (111), (220) crystal orientation, and the (220) crystal orientation became strong along with electroplating time and current density, but weak with the proportion of AlCl 3 in baths. On the contrary, the changes of the (111) orientation exhibited an opposite trend.

Currently, synthesis of most porous organic frameworks (POFs) requires noble metals as the main catalyst. Herein we report a low-cost and straightforward synthetic strategy to develop porous aromatic frameworks (PAFs). With AlCl3 as the catalyst, the Scholl coupling reaction could occur between the phenyl rings of aromatic compounds. Using 3-dimensional monomers, such as triphenylamine, tetraphenylmethane, tetraphenylsilane, and tetraphenylgermane, we successfully obtained a series of PAFs with moderate Brunauer–Emmett–Teller (BET) surface areas ranging from 515 m2 g−1 to 1119 m2 g−1. Among the obtained PAF materials, PAF-41 exhibited the best CH4 and CO2 sorption capacity with CH4 (1.04 mmol g−1) and CO2 (3.52 mmol g−1) at 273 K. In addition, PAF-43 demonstrated its comparably high isosteric heat of adsorption at 34.8 kJ mol−1 for CO2 and 29.7 kJ mol−1 for CH4. It is also worth mentioning that the developed approach also overcomes typical flaws of some classic PAFs, such as high cost and complexity of precursor preparation.

Tonalid, an important fragrance ingredient with widespread application, was synthesized via two Friedel-Crafts reactions, which were catalyzed by AlCl 3 . The traditional tonalid production was conducted in batch stirring tank reactors, suffering from low production capacity and the safety hazard of temperature runaway. To solve these problems, the continuous-flow technologies were developed for the high-efficiency and intrinsically safe synthesis of tonalid in microreactors. Catalyst AlCl 3 was neatly homogenized in proper solvents by forming complex with reactant, which was a necessary step for the continuous synthesis in microreactors. Several reaction conditions, including reactant molar ratio, catalyst concentration, temperature, and microchannel hydrodynamic diameter, were investigated for the two Friedel-Crafts reactions in microreactors. At optimized conditions, the yields of the two Friedel-Crafts reactions were 44.15% and 97.55%, respectively. In comparison with the batch reactors, the reaction times of these two reactions could both be reduced by nearly two thirds in microreactors at the similar yield.
