A multifunctional Zr-containing catalyst (FM-Zr-ARS) was successfully synthesized by a modulated hydrothermal synthesis route. Systematic characterization results supported the presence of robust porous inorganic-organic frameworks stabilized by the strong coordination interaction of Zr4+ with oxygen-rich functional groups in Alizarin red S (ARS). Moreover, the -O-Zr-O- network in the FM-Zr-ARS structure formed a rich content of acid-base sites. In addition, the inherent sulfonic groups in ARS made the FM-Zr-ARS hybrids possess Bronsted acid sites. Therefore, under the synergistic catalysis of the multiple functional sites, FM-Zr-ARS showed remarkably high catalytic activity for γ-valerolactone (GVL) production from levulinate esters and furfural. Finally, 72.4% and 97.7% yields of GVL were obtained in the conversion of furfural and Et levulinate, resp., after 8 h of reaction at 433 K. On the basis of the role of different functional sites, a plausible catalytic mechanism was presented for the conversion of biomass-derived furfural to GVL.

Author is Robichaux, Laura; Kendell, Shane.

A one-step direct alkylation method for synthesizing Bu levulinate from Bu alc. and furfuryl alc. has been explored. This process is carried out under reflux, at ∼ 120 °C for 2 h and utilizes a catalyst. Catalysts are based on phosphotungstic acid; the catalysts are modified via cation exchange, producing several cesium, copper and silver based phosphotungstates. Of these, the greatest activity and selectivity towards Bu levulinate was achieved over the Cu0.5H2[PW12O40] catalyst, with 100% conversion and a Bu levulinate selectivity of 69%. Various side reactions are also observed, with products that may also be suitable for biofuel applications. A detailed product anal. has been performed, and likely reaction schemes for these products have been determined Overall, these results demonstrate an efficient method for Bu levulinate production from biomass-derived sources.

Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about Effect of infrared ray roasting on oxidation stability and flavor of virgin rapeseed oils.

Effects of IR ray roasting (IRR) on the oxidation stability and flavors of virgin rapeseed oil (VROs) at 110-170°C were investigated and compared with traditional roller roasting (TRR). Results showed that IRR samples showed lower acid and peroxides values, higher oxidation stability index, and 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity than TRR ones. IRR samples displayed better thermal expansion of rapeseed for internal fragmentation from microstructures, which facilitated the release of tocophenols (652.63-748.78 mg/kg) and 4-vinylsyringol (7.54-678.19 mg/kg), compared with TRR ones with tocophenols (652.63-689.28 mg/kg) and 4-vinylsyringol (7.54-524.18 mg/kg) contributing to better oxidation stability. Moreover, important volatile compounds, including pyrazines, isothiocyanates, nitriles and aldehydes, were formed quant. more in IRR than TRR samples, which was attributed to better heat transfer efficiency and internal fragmentation promoting complex reactions inside rapeseed. Therefore, IRR has more pos. roasting effects on VROs than TRR.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 591-12-8, is researched, Molecular C5H6O2, about Elucidation of surface active sites by formic acid adsorbed IR studies in the hydrogenation of levulinic acid to valeric acid over rare earth metal doped titania supported nickel catalysts, the main research direction is formate adsorbed IR hydrogenation levulinate valerate titania supported catalyst.Name: 5-Methylfuran-2(3H)-one.

Titania supported Ni catalyst modified by different lanthanides (La, Ce, Pr and Nd) were evaluated for the one-step conversion of levulinic acid (LA) to valeric acid (VA) using formic acid as a hydrogen source. Among these, the La modified Ni/TiO2 demonstrated better VA yields with an optimum LA to VA mole ratio of 1:3. Pyridine and/or formic acid adsorbed IR studies revealed that presence of weak Lewis and strong basic sites present on the Ni-La/TiO2 surface was the reason for higher VA selectivity. The physicochem. characteristics of the modified Ni-M/TiO2 (M = La, Ce, Pr and Nd) catalysts deduced from H2-TPR, N2O titration, TPD of NH3 and catalytic activity data emphasized a combination of metallic Ni with surface acid-base sites were responsible for the formation of VA in single step. Using aqueous γ-valerolactone, 99% selectivity towards VA was achieved. A plausible reaction mechanism has been proposed based on the kinetic data obtained at moderate temperatures and ambient pressures.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Zhang, Zhenwei; Wang, Peng; Wu, Zeying; Yue, Chuanjun; Wei, Xuejiao; Zheng, Jiwei; Xiang, Mei; Liu, Baoliang researched the compound: 5-Methylfuran-2(3H)-one( cas:591-12-8 ).Name: 5-Methylfuran-2(3H)-one.They published the article 《Efficient synthesis of niobium pentoxide nanowires and application in ethanolysis of furfuryl alcohol》 about this compound( cas:591-12-8 ) in RSC Advances. Keywords: niobium pentoxide nanowire furfuryl alc ethanolysis. We’ll tell you more about this compound (cas:591-12-8).

Nb2O5 nanowires with high sp. surface area and crystallinity were prepared by using ammonium oxalate and an acetic acid solvent system. The nanomaterial was applied in ethanolysis of furfuryl alc. (FA), and the yield of the product, 2-(ethoxymethyl)furan (FEE), achieved was up to 79.6%. Compared to mesoporous Nb2O5 materials and other porous materials, the residence time of FEE on the surface of the catalyst is shorter, and the yield of Et levulinate (EL) is lower. Furthermore, a high temperature calcination treatment can change the acid sites and acidity type distribution on the nanowire surface. By XRD, NH3O5 -TPD, IR, and TG-DTA determination methods, it was found that the weak and medium-strong acid sites on the surface of Nb2O5 nanowires were reduced after a 300°C treatment, and the amount of strong acid was relatively higher. According to the catalytic performance test data and acidity determination, it was concluded that more weak acid and medium-strong acid sites improve the conversion of furfuryl alc. to FEE, and the strong acid sites promote further conversion of FEE to EL.

Synthetic Route of C5H6O2. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5-Methylfuran-2(3H)-one, is researched, Molecular C5H6O2, CAS is 591-12-8, about An approach to identifying fibers and evolved compounds from flame resistant fabrics. Author is McPartlin, Michael W.; Italiano, Brandon R.; Tiano, Thomas M.; Pilkenton, Sarah J.; Lawton, Timothy J..

Flame resistant (FR) fabrics have use in civilian, military, and industrial applications. This work describes the development of a methodol. aimed at identifying the fiber composition of blended fabrics of unknown composition Here, FR fabrics used in military uniforms, are studied using a combination of XPS, isothermal thermogravimetric anal. (TGA) and pyrolysis gas chromatog./mass spectrometry (Py-GC-MS). Elemental anal. of the fabrics using XPS yielded a preliminary determination of the composition of the polymer(s) and aided in the identification of FR additives. TGA and Py-GC-MS experiments were used for subsequent compound identification. In TGA the temperature of mass loss events was compared to reference materials, and in Py-GC-MS the pyrolysis products of the blended FR fabrics were compared to those from a series of potential parent fibers. It was possible to discern the composition of the parent fibers and the type of FR treatment added to fabrics because the thermal decomposition chem. did not significantly change by blending the fibers to make fabrics.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Transfer Hydrogenation of Methyl and Ethyl Levulinate Promoted by a ZrO2 Catalyst: Comparison of Batch vs. Continuous Gas-Flow Conditions, published in 2019-06-03, which mentions a compound: 591-12-8, Name is 5-Methylfuran-2(3H)-one, Molecular C5H6O2, Recommanded Product: 591-12-8.

The catalytic conversion of Me and Et levulinates into γ-valerolactone (GVL) by using methanol, ethanol, and 2-propanol as the H-donor/solvent, promoted by the ZrO2 catalyst, is described as carried out under both batch and gas-flow conditions. Under batch conditions, 2-propanol was found to be the best H-donor mol., with Et levulinate giving the highest yield in GVL. The reactions occurring under continuous gas-flow conditions were found to be much more efficient, also showing excellent yields in GVL when EtOH was used as the reducing agent. These experiments clearly show that the ability to release hydrogen from the alc. H-donor/solvent is the main factor driving CTH processes, while the tendency to attack the esteric group is the key step in the formation of transesterification products.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 5-Methylfuran-2(3H)-one(SMILESS: O=C1OC(C)=CC1,cas:591-12-8) is researched.Name: 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride. The article 《Enhanced activity of Ru-Ir nanoparticles over SiC for hydrogenation of levulinic acid at room-temperature》 in relation to this compound, is published in Materials Research Bulletin. Let’s take a look at the latest research on this compound (cas:591-12-8).

The hydrogenation of levulinic acid (LA) to γ-valerolactone (GVL) under mild condition is a promising but challenging process. Herein, SiC supported Ru-Ir bimetallic catalyst exhibit enhanced catalytic activity for aqueous hydrogenation of LA into GVL under mild conditions. Comparing with monometallic Ir3/SiC and Ru3/SiC, the conversion of LA over bimetallic Ru0.5-Ir2.5/SiC catalyst increase from 51.2% and 45.9% to 100% at 25°C and 0.2 MPa of H2 pressure. The enhanced catalytic activity of Ru0.5-Ir2.5/SiC catalyst originates from the electronic synergistic effect among Ru, Ir and SiC. Due to the electron transfer, electron-richened Ir nanoparticles show stronger ability for H2 dissociation, and the SiC surface produces more active sites to accommodate hydrogen species that spill over from Ir and Ru. The adsorption and hydrogenation of LA mols. occur on the surface of SiC.
