Considerable progress has been made recently in the catalytic conversion of renewable biomass resources to Me lactate (MLA). However, conceiving eco-friendly and effective catalytic systems for the production of MLA from biomass carbohydrates remains a key challenge. Herein, we report a multifunctional catalyst Sn(salen)/IL, consisting of a Sn(salen) complex and an imidazolium-based ionic liquid (IL), which acts via an intramol. synergistic effect to convert carbohydrates to MLA in methanol. The versatile properties of the resultant catalyst were revealed to be responsible for the conversion of fructose to MLA and the efficient suppression of undesired side reactions. This catalyst displayed outstanding catalytic activity, high selectivity, and excellent recyclability, giving an MLA yield of up to 68.9 % at 160 °C after 2 h. The results of this study will contribute to new approaches for designing synergistic catalysts for producing liquid fuels and chems. from biomass resources.

And the article was included in Journal of Physical Chemistry C in 2017.Application In Synthesis of 3-Dodecyl-1-methyl-1H-imidazol-3-ium bis((trifluoromethyl)sulfonyl)amide This article mentions the following:

The tribol. behavior of a silica/silicon tribopair lubricated with anhydrous fluorinated ionic liquids was investigated by pin-on-disk tribometry. A first series of tests was designed to detect the onset of surface damage as a function of sliding speed. 1-ethyl-, 1-hexyl-, and 1-dodecyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM] TFSI, [HMIM] TFSI, and [DDMIM] TFSI, resp.), and 1-ethyl-3-methylimidazolium tris(perfluoroethyl)trifluorophosphate ([EMIM] FAP) were selected as lubricants. Elastohydrodynamic lubrication (EHL) predictive formulas for min. film thickness (h0 EHL) were used to estimate the value of the critical h0 EHL at the transition to mixed lubrication, which was identified on the basis of the variations observed in friction upon decreasing the sliding speed. Taking into account the composite roughness of the counterparts (Rq ∼ 1.1 nm), the differences in the critical values of h0 EHL measured for the various ILs are suggested to reflect changes in the interfacial structure of the confined ILs. In particular, the possible effects associated with the alkyl chain attached to the imidazolium cation or with the type of anion are discussed on the basis of models of the IL-solid interface presented in the recent literature. The second part of the investigation focuses on the tribol. behavior observed with a SiO2/Si tribopair lubricated with 1-ethyl- and 1-hexyl-3-methylimidazolium-based bis(trifluoromethylsulfonyl)imide ILs under boundary conditions. Tests were carried out under conditions that prevent fluid-film lubrication, so as to allow the study of the boundary-lubrication regime over an extended range of speed. The mechanism of wear was investigated on the basis of a chem., structural, and topog. anal. of the worn surfaces. The prevailing mode of surface damage is described on the basis of a comparison with results previously obtained in tests of other imidazolium-based ILs as lubricants for the same tribopair. The new results revealed some further important details on the relationship between the chem. structure of the IL and the wear mechanism of the investigated tribopair.

In this paper, the effect of final pyrolysis temperature on the yield of products from the pyrolysis of sewage sludge was studied. The light fraction from sludge pyrolysis oil was analyzed. The fundamental properties of the pyrolysis residues were also investigated briefly. The results showed that when the final pyrolysis temperature was between 450 °C to 500°C, the yield of liquid product was favorable. With the increase of final pyrolysis temperature, the decreasing trend of pyrolysis residue was similar to the increasing trend of liquid product. Both of them were steep when the temperature was under 450°C and mild when the temperature was higher than 450°C. Meanwhile the uncondensed gas increased smoothly with the increase of final pyrolysis temperature The light fractions of pyrolysis oil obtained at 450°C was mainly consisted of alkanes, alkenes, nitriles and nitrogen-containing heterocyclic compounds as well as MAHs etc. Among them, the concentration of toluene, 4-methyl-phenol, 1-methyl-2, 5-pyrrolidinedione, pyridine, 1-dodecene and pentadecane etc. were significant. The pyrolysis residues of sewage sludge contained low carbon and high ash. However, they still possessed some volatile content. With the increase of final pyrolysis temperature, the surface of pyrolysis residue became more and more looser and rougher.

Thermochem. treatments are traditionally employed to perform the separation between the oil and water phases in the petroleum industry. The chem. agents have the function of reducing the barrier rigidity formed by natural surfactants present in the emulsion, thus favoring destabilization. The main objective of this study was to analyze the viscoelastic properties of samples composed of water and a crude oil with the addition of distinct ionic liquids The methodol. used to obtain the interfacial properties was the pedant drop technique. The results showed that the addition of the ionic liquids induced a reduction in the interfacial elasticity and an increase in the compressibility of interfacial films. It was also observed that an enhancement in the alkyl chain length has a pos. effect on changing the interfacial properties.

And the article was included in ChemSusChem in 2021.Computed Properties of C8H8N2 This article mentions the following:

Although the power conversion efficiencies (PCEs) of perovskite solar cells (PSCs) have made great progress, the surface and interface defects still affect their PCE and stability and hinder the commercialization. To overcome this problem, 1-methylimidazole (1-MIm) and 1-methylbenzimidazole (1-MBIm) were used as the interfacial passivation agents to passivate the defects at surface and interface. The results indicated that, in contrast to 1-MIm, 1-MBIm displayed a stronger Lewis coordination interaction with the uncoordinated Pb2+ to reduce the non-radiative recombination and also effectively improved the charge transfer capacity of perovskite films due to its strong Π-Π conjugate interaction, resulting in the better photovoltaic performance. As a result, the PCE of the champion 1-MBIm PSC was improved from 19.48 (pristine) to 21.22 % with a dramatically enhanced open-circuit voltage (Voc=1.15 V). More importantly, a significant improvement in long-term stability was achieved for 1-MBIm perovskite devices, which was attributed to the high-quality perovskite film caused by the strong passivation effect of 1-MBIm and the hydrogen bond with water mols. The results offers an efficient and facile strategy by interface engineering to fabricate high-performance and stable PSCs for com. application.

The role of cation and the influence of the cation alkyl chain length of vinylimdazolium-based ionic liquid (IL) were studied previously to develop high-performance shale inhibitor for application in water-based drilling fluids (WBDFs). Results demonstrate that they have a considerable effect on the inhibition performance. However, the physicochem. properties can be tuned by changing the cation/anion combination. Therefore, the influence of anion type on the inhibiting performance must be investigated. In this study, we selected several vinylimdazolium-based ILs with different anions, such as bromide (Br-), tetrafluoroborate (BF-4), hexafluorophosphate (PF-6), and bis(trifluoromethylsulfonyl) (TFSI-). The size, solubility, hydrophilicity, and interaction in-between were tuned accordingly by changing the anion species. Results from linear swelling height, hot rolling recovery, and rheol. measurements show that the IL with bromide anion has the most outstanding shale inhibiting performance. The anions influence the inhibitory performance of ILs in a distinct manner from cations by measuring the properties of Na-Bent dispersions added with different anion-based ILs. The former produces different abilities to suppress elec. double layers and decreases the interlayer distance, whereas the latter mainly affects the interlayer distance. Despite different hydrophilic/hydrophobic properties, they have similar performance to inhibit the crystalline hydration and swelling. This condition is probably because they have a common cation that dominates the process of entering the interlayer void and narrowing interlayer spacing. Many hydrophilic ILs with anion Br- or BF-4 have the capacity to strongly resist the repel interaction between clay particles and prompt aggregation, leading to better inhibitory performance. Combined with the previous result, cations and anions affect the IL inhibiting ability although their underlying mechanism is different. Thus, this work explored the relationship between inhibiting performance and IL moiety. The findings provide consolidate theor. foundation for developing shale inhibitors for WBDFs.

A simple and green protocol was developed for the reductive cyclization of o-phenylenediamine with CO2 and BH3NH3 to yield 1H-benzimidazole. The desired 1H-benzimidazole derivatives were produced under mild conditions. Mechanism investigation indicated that the coordination of o-phenylenediamine with the boron atom of BH3NH3 promoted the transfer of the formyl group to form a stable intermediate, which facilitated the intramol. nucleophilic addition-elimination for the formation of target product. In this process, BH3NH3 served multifunctional roles, acting as a reducing agent and a formylation catalyst. In the experiment, the researchers used many compounds, for example, 7-Methyl-1H-benzo[d]imidazole (cas: 4887-83-6COA of Formula: C8H8N2).

7-Methyl-1H-benzo[d]imidazole (cas: 4887-83-6) belongs to imidazole derivatives. 1H-imidazole is an imidazole tautomer which has the migrating hydrogen at position 1. It is a conjugate base of an imidazolium cation. It is a conjugate acid of an imidazolide. It is a tautomer of a 4H-imidazole. Imidazole has been usedin the lysis, wash and elution buffer for the purification of histidine tagged Sonic Hedgehog(shh-N) protein, in elution buffer in stepwise gradient for the purification of histidine tagged aldo keto reductases using nickel affinity chromatography, as a component of homogenization buffer for the purification of phagosomal compartments from dendritic cells.COA of Formula: C8H8N2
