TiO(2)supported Ru catalysts for the hydrogenation of succinic acid: influence of the support

Succinic acid is a valuable biomass-derived platform molecule, which can be further catalytically converted into many industrially relevant molecules such as gamma-butyrolactone, 1,4-butanediol or tetrahydrofuran. The influence of the support nature on both the activity of Ru/TiO(2)catalysts and the selectivity pattern in the hydrogenation of succinic acid was investigated, with focus on the metal-support interaction, the crystallographic structure of the TiO(2)support and the supported Ru nanoparticle size features. We showed that the catalyst activity was related to both the Ru particle size and the metal support interaction, those features being induced by the presence of the rutile phase within the TiO(2)support and by the preparation method of the supported Ru particles. The rutile phase not only favors the formation of small Ru particles but also promotes stronger metal-support interaction compared with the anatase polymorph. Strong interactions between metal and support can also be formedviathermal reduction in contrast to low-temperature direct chemical reduction. Interestingly, a low temperature solar photon-assisted synthesis method facilitates very high succinic acid conversion, by enabling the stabilization of 1.8 nm small-size Ru nanoparticles in the absence of any rutile phase within the TiO(2)support.

Alkali Metal Reduction of 1,2-Bis[(2,6-dibenzhydryl-4-methylphenyl)imino]acenaphthene (Ar-BIG-bian) to Radical-Anion

Reduction of Ar-BIG-bian (1, 1,2-bis[(2,6-dibenzhydryl-4-methylphenyl)imino]acenaphthene) with one molar equivalent of Li, Na or K in tetrahydrofuran (THF) affords corresponding radical-anionic salts (Ar-BIG-bian)M(THF) (M=Li, 2; Na, 3; K, 4). Compounds 2-4 were isolated in good yields and characterized by the elemental analysis, IR and ESR spectroscopy as well as the single-crystal X-Ray analysis. Bulky Ph-2(H)C groups in Ar-BIG-bian ligand prevent dimerization of complexes 2-4 and limit a number of coordinated THF molecules to one. In all three products a saturation of the alkali metal coordination sphere is achieved through an interaction with Ph rings of Ph-2(H)C substituents.

Direct conversion of sugar into ethyl levulinate catalyzed by selective heterogeneous acid under co-solvent system

The direct synthesis of ethyl levulinate (EL) from sucrose was investigated under co-solvent of tetrahydrofuran (THF)/ethanol over stable/active heterogeneous acid catalyst. Several Lewis acid-metal oxides were doped onto Bronsted acid-sulfonated carbon (SC) and the results found that Zn-SC exhibited highest activity for production of EL from sucrose conversion of 100% with a selectivity of 72.1%. The catalytic mechanism for conversion of sucrose into EL and other products was investigated through significant effects such as catalyst type, co-solvent and ultrasonic application. The catalyst reusability test exhibited high stability for five cycles and then dramatically decreased without any regeneration process.

Temperature and Solvent Effects on H-2 Splitting and Hydricity: Ramifications on CO2 Hydrogenation by a Rhenium Pincer Catalyst

The catalytic hydrogenation of carbon dioxide holds immense promise for applications in sustainable fuel synthesis and hydrogen storage. Mechanistic studies that connect thermodynamic parameters with the kinetics of catalysis can provide new understanding and guide predictive design of improved catalysts. Reported here are thermochemical and kinetic analyses of a new pincer-ligated rhenium complex ((POCOP)-P-tBu)Re(CO)(2) ((POCOP)-P-tB-P-u = 2,6-bis(di-tert-butylphosphinito)phenyl) that catalyzes CO2 hydrogenation to formate with faster rates at lower temperatures. Because the catalyst follows the prototypical outer sphere hydrogenation mechanism, comprehensive studies of temperature and solvent effects on the H-2 splitting and hydride transfer steps are expected to be relevant to many other catalysts. Strikingly large entropy associated with cleavage of H-2 results in a strong temperature dependence on the concentration of [((POCOP)-P-tB-P-u)Re(CO)(2)H](-) present during catalysis, which is further impacted by changing the solvent from toluene to tetrahydrofuran to acetonitrile. New methods for determining the hydricity of metal hydrides and formate at temperatures other than 298 K are developed, providing insight into how temperature can influence the favorability of hydride transfer during catalysis. These thermochemical insights guided the selection of conditions for CO2 hydrogenation to formate with high activity (up to 364 h(-1) at 1 atm or 3330 h(-1)( )at 20 atm of 1:1 H-2:CO2). In cases where hydride transfer is the highest individual kinetic barrier, entropic contributions to outer sphere H-2 splitting lead to a unique temperature dependence: catalytic activity increases as temperature decreases in tetrahydrofuran (200-fold increase upon cooling from 50 to 0 degrees C) and toluene (4-fold increase upon cooling from 100 to 50 degrees C). Ramifications on catalyst structure-function relationships are discussed, including comparisons between outer sphere mechanisms and metal-ligand cooperation mechanisms.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 713-95-1, in my other articles.

Effect of solvent on crosslinking of a polyimide membrane using the liquid-phase crosslinking process for CO2/CH4 separation

The crosslinking within a polyimide membrane was investigated by means of a liquid-phase crosslinking process (L-PCP) in which a polymer and crosslinker are mixed in a solvent to prepare crosslinked membranes in a single step. To prepare crosslinked membranes, the polyimide polymer was dissolved in various solvents including tetrahydrofuran (THF), chloroform, dimethylsulfoxide (DMSO), dimethylformamide (DMF), and N-methylpyrrolidone (NMP) with p-phenylenediamine as a crosslinker, and the crosslinked membranes were then obtained by casting the polymer solution. The crosslinked membranes showed different degrees of crosslinking according to the solvent (NMP > DMF > DMSO > THF > chloroform). The highest degree of crosslinking was obtained with the membrane crosslinked in NMP, which also presented the best chemical stability and plasticization resistance against condensable CO2 gas. On the other hand, the membranes crosslinked in THF and chloroform exhibited poor chemical stability and plasticization resistance. This difference in crosslinking degrees arising from the use of various solvents can be correlated with solubility parameters of the polymer and solvent. A good solvent can swell the polymer chains and provide higher crosslinker diffusivity and more effective crosslinking conditions, and vice versa. For CO2/CH4 separation, the highest CO2 permeability was obtained from the crosslinked membrane in THF and chloroform (-8.2 barrer) with a modest CO2/CH4 selectivity of 35 at high pressure (30 barg) despite plasticization. Moreover, the highest CO2/CH4 selectivity (-39) could be obtained with the membranes crosslinked in DMSO and DMF with CO2 permeability of 5 barrer. The membrane crosslinked in NMP exhibited the lowest CO2 permeability of 2.8 barrer at 30 barg due to the highly inter-crosslinked polymer structure, which hinders gas diffusion.

A post-synthetically reduced borane-functionalised metal-organic framework with oxidation-inhibiting reactivity

The first post-synthetic reduction of a ketone-containing metal-organic framework (MOF) is reported. The borane tetrahydrofuran complex (H3B center dot THF) quantitatively reduced a ketone functional group in a porous zinc(II) IRMOF-9 scaffold at room temperature. Single crystal X-ray diffraction studies established that the crystallinity and interpenetration mode of the framework are preserved during reduction. Boron remains bound in the framework and can be removed via mild acid treatment to yield a MOF with identical properties to that prepared by direct synthesis. The boron-functionalised MOF was unable to reduce benzaldehyde but instead was found to inhibit benzaldehyde autooxidation.

Suppression of methane hydrate dissociation from SDS-dry solution hydrate formation system by a covering liquid method

Prevention of gas hydrate dissociation made potential application of gas storage and transportation by hydrate-based technology. In this work, a covering liquid method was proposed to prevent methane (CH4) hydrate dissociation when methane hydrate formed in sodium dodecyl sulfate (SDS)-dry solution system. The covering liquids were cyclopentane (CP), cyclohexane, and tetrahydrofuran (THF), respectively. The results showed that CP and THF can effectively prevent methane hydrate dissociation at 266.0 K, while cyclohexane failed to prevent methane hydrate dissociation at the same temperature. Methane hydrate dissociated percentage was 25.5% (0.61 MPa) after 12 h of dissociation at 266.0 K, which can be reduced to 20.0% (0.24 MPa) and 13.8% (0.30 MPa) by covering CP and THF, respectively. All three covering liquids can prevent methane hydrate dissociation at 272.2 K, and methane hydrate dissociated percentage decreased from 71.1% (1.33 MPa) without covering liquid to 49.1% (0.82 MPa), 36.4% (0.64 MPa), and 30.4% (0.63 MPa) by covering CP, cyclohexane, and THF, respectively. However, when methane hydrate dissociated temperature increased to 274.2 K, all three covering liquids failed to prevent initial methane hydrate dissociation, but suppressed later stage of methane hydrate dissociation by forming binary hydrate.

Non-porous organic crystals and their interaction with guest molecules from the gas phase

Some organic molecules encapsulate solvents upon crystallization. One class of compounds that shows a high propensity to form such crystalline solvates are tetraaryladamantanes (TAAs). Recently, tetrakis(dialkoxyphenyl)-adamantanes have been shown to encapsulate a wide range of guest molecules in their crystals, and to stabilize the guest molecules against undesired reactions. The term ‘encapsulating organic crystals’ (EnOCs) has been coined for these species. In this work, we studied the behavior of three TAAs upon exposition to different guest molecules by means of sorption technique. We firstly measured the vapor adsorption/desorption isotherms with water, tetrahydrofuran and toluene, and secondly, we studied the uptake of methane on dry and wet TAAs. Uptake of methane beyond one molar equivalent was detected for wet crystals, even though the materials showed a lack of porosity. Thus far, such behavior, which we ascribe to methane hydrate formation, had been described for porous non-crystalline materials or crystals with detectable porosity, not for non-porous organic crystals. Our results show that TAA crystals have interesting properties beyond the formation of conventional solvates. Gas-containing organic crystals may find application as reservoirs for gases that are difficult to encapsulate or are slow to form crystalline hydrates in the absence of a host compound.

An electrode-level prelithiation of SiO anodes with organolithium compounds for lithium-ion batteries

Silicon monoxide (SiO) is considered an attractive alternative to conventional graphite anodes due to its high specific capacity and good cycling performance. However, it suffers from low initial Coulombic efficiency (ICE) due to a large irreversible capacity and large volume change during cycling. Both deficiencies hinder the commercial use of SiO anodes. A new organolithium compound (Li-9,9-dimethyl-9H-fluorene-tetrahydrofuran) with lower redox potential is reported to prelithiate a SiO-based anode. An SEI layer is formed during prelithiation and a controllable amount of reversible lithium is preloaded into the SiO electrode. The ICE of a prelithiated SiO-based electrode in half-cell format is increased greatly to similar to 90.7%. When matched with a LiNi0.6Co0.2Mn0.2O2 cathode, the full cell with the prelithiated SiO/G anode exhibits a much improved ICE in comparison with the pristine one (87.1% vs. 61.1%). This facile prelithiation method is proved to be a practical solution for the commercial application of SiO-based materials.
