Selective conversion of 5-hydroxymethylfurfural (HMF) can produce sustainable fuels and chemicals. Herein, Cu-ZnO catalysts derived from minerals (malachite, rosasite and aurichalcite) were employed for selective hydrogenation of HMF for the first time. High yields of 2,5-dihydroxymethylfuran (~99.1%) and 2,5-dimethylfuran (~91.8%) were obtained tunably over the catalyst with a Cu/Zn molar ratio of 2, due to the well-dispersed metal sites tailored by mineral precursors, well-controlled surface sites and optimized reaction conditions. The relationship between catalytic performance and catalyst properties was elucidated by characterization based on the composition and the structural and surface properties, and catalytic tests. The catalyst can also be extended to selective hydrogenation of other bio-derived molecules (furfural and 5-methylfurfural) to target products. The construction of mineral-derived Cu-ZnO catalysts and the revelation of the structure-performance relationship can be applied to further rational design and functionalization of non-noble Cu catalysts for selective conversion of bio-derived compounds.

Chemistry is traditionally divided into organic and inorganic chemistry. Recommanded Product: 2144-40-3, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 2144-40-3

Catalytic activity and selectivity of Ni, Pd, and Cu supported on gamma-alumina catalysts for the 5-hydroxymethylfurfural hydrodeoxygenation in aqueous phase were studied in this work. The catalysts were prepared by incipient wetness impregnation and characterized by BET surface area, ICP-OES, dynamic chemisorption, temperature-programmed reduction, and ATR-IR. The reactions were carried out in a downflow reactor at a hydrogen pressure of 0.41 MPa and a temperature range of 137-189 C. A variety of valuable compounds were obtained depending on the nature of the metal deposited on the support. Ni and Pd-supported catalysts were selective toward products of the decarbonylation reaction of the HMF carbonyl group, whereas hydrogenolysis products were observed on Cu-supported catalyst. Additionally, the Pd-supported catalyst was quite selective to hydrogenate the furan ring, especially at high temperatures.

Application of 2144-40-3, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other?

2,5-Dimethylfuran (DMF) is an attractive biofuel being stable, insoluble in water and an alternative to gasoline. DMF is accessible via hydrodeoxygenation of the cellulosic bio-based platform chemical 5-hydroxymethylfurfural (HMF). Efficient transformations of HMF to DMF have been reported to date; however, the kinetics of the reaction and a comprehensive analysis of the reaction network have not been addressed yet. In the present work, a plausible reaction network based on kinetic study of the hydrodeoxygenation of HMF over a carbon-supported nickel catalyst is proposed. The study of the reaction network showed the reaction indeed proceeds via the hydrogenation of the aldehyde group of HMF to form 2,5-bishydroxymethylfuran (BHMF) and subsequent conversion of BHMF to 5-methylfurfurylalcohol (MFA) followed by hydrogenolysis of MFA to DMF. Side reactions include the formation of 2,5-dihydroxymethyltetrahydrofuran (DHMTHF) and 2,5-dimethyltetrahydrofuran (DMTHF). A suitable kinetic model enabled estimating the kinetic parameters in the reaction temperatures range of 150?190 C. Kinetics analysis revealed the hydrogenation of HMF to BHMF as rate-determining step, while subsequent deoxygenation to DMF proceeds faster. Interestingly, most undesired reactions were kinetically hindered under selected reaction conditions allowing high selectivity to the target product DMF.

Lignocellulosic biomass can be converted to significant platform molecule 5-hydroxymethylfurfural (HMF), from which one can envision a number of biofuels and chemicals through either chemical or biological conversions. Chemoselective hydrogenation is one of the important pathways for the upgrading of HMF into furanyl diols consisting of 2,5-bis(hydroxymethyl)furan (BHMF) and 2,5-bis(hydroxymethyl)tetrahydrofuran (BHMTHF). BHMF and BHMTHF are all-purpose intermediates for the manufacture of chemicals, fuels, and functional materials. In this context, we comprehensively summarized the studies on the chemoselective hydrogenation of HMF into furanyl diols in terms of different H-donors, including molecular H2, alcohols, formic acid, and other alternative H-donors. Through the systematic survey of the previous works, a feasible research direction is discussed for the production of furanyl diols.

Aqueous hydrogenation of 5-hydroxymethylfurfural (HMF) was performed over the RuPd/graphene (RGO) bimetallic catalyst at room temperature (20 C). The combination of Pd and Ru gave the best catalytic performance for the complete hydrogenation of HMF to 2,5-dihydroxymethyltetrahydrofuran (DHMTHF) compared with the corresponding monometallic Ru/RGO and Pd/RGO catalysts. The yield of DHMTHF reached 92.9% over the RuPd/RGO catalyst, while it was 6.0% and 4.1% over the monometallic Ru/RGO and Pd/RGO catalyst, respectively. High-resolution TEM (HRTEM), high-angle annular dark-field STEM (HAADF-STEM), and H2-TPR identified the formation of RuPd alloy in RuPd/RGO catalyst. The strong interaction between Ru and Pd caused the formation of Rudelta–Pddelta+ pairs, as made evident by XPS. The DFT calculations revealed that the electron feedback was from the furan ring of HMF and the intermediate product 2,5-dihydroxymethylfuran (DHMF) to the electron-deficient Pddelta+ species in Rudelta–Pddelta+ pairs. Accordingly, the high efficiency of RuPd/RGO catalyst in the hydrogenation of HMF to DHMTHF results from the electron transfer circle between the Rudelta–Pddelta+ pairs and HMF molecules, i.e., the electron transfer from Rudelta- to the C=O group of HMF and the electron feedback from the C=C bond in the furan ring of HMF to the electron-deficient Pddelta+ species in Rudelta–Pddelta+ pairs.

Polymers are used in simple consumer items like carpets, furniture, glues, and clothing but are also used in advanced engineering, including materials used in the aerospace industry. Therefore, polymers and consequently their monomers play an important role in our everyday life. Currently, most of the monomers are produced from fossil resources, the supply of which is diminishing. In this paper we review strategies and catalytic processes to obtain currently used and potentially new monomers from renewable bio-based feedstocks and platform chemicals. This Review is divided by type of monomer and includes diacids and esters, diols, hydroxy acids and esters, lactones, carbonates, cyclic ethers, diamines, amino acids and lactams, alkenes, acrylics, and conjugated dienes. Only routes based on the use of homogeneous catalysis, heterogeneous catalysis, or bio-catalysis are described. Fermentative processes are not discussed.

The metal catalyzed hydrogenolysis of the biomass-derived THF-dimethanol to 1,2,6-hexanetriol using heterogeneous catalysts was investigated. Bimetallic Rh-Re catalysts (4 wt% Rh and a Re/Rh (mol. ratio of 0.5) on a silica support gave the best performance and 1,2,6-hexanetriol was obtained in 84% selectivity at 31% conversion (120 C, 80 bar, 4 h); the selectivity reaches a maximum of 92% at 80 C. The product distribution at prolonged reaction times or higher temperatures or both shows the formation of diols and mono-alcohols, indicating that the 1,2,6-hexanetriol is prone to subsequent hydrodeoxygenation reactions. Different silica supports were investigated and optimal results were obtained with an amorphous silica featuring an intermediate surface area and an average mesopore size of about 6 nm. TPR and XPS surface analysis support the presence of mixed Rh and Re particles. The redox Redelta+/ReTotal surface ratio correlates with the conversion in a volcano type dependency. Both gas phase as well as Rh200Re1OH cluster DFT calculations support an acid-metal bifunctional mechanism and explain the products distribution.

Application of 2144-40-3, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 2144-40-3, molcular formula is C6H12O3, introducing its new discovery.

Saturated cyclohexene water was used as the reductant for the preparation of Pd/MIL-101(Cr). The catalysts were characterized by XRD, N2 adsorption/desorption isotherms, XPS, TEM, FTIR, ICP-AES and in-situ FTIR spectra of adsorbed pyridine. The water saturated by cyclohexene was proved to be an effective reductant to produce metallic Pd catalyst. The texture of MIL-101(Cr) was kept well after the introduction of Pd to MIL-101(Cr). The hydrogenation of HMF to 1-hydroxy-2,5-hexanedione (HHD) was conducted in water using Pd/MIL-101(Cr) as catalyst. After reacted for 6 h at 413 K 4 MPa H2, up to 82% yield of HHD was achieved without acid additives. The MIL-101(Cr) acted both as support and acid catalyst generated from the open Cr3+. The stability of the catalyst was investigated to find that the TOFs decreased slightly after the catalyst was used. The decline in the catalytic activity was discussed and ascribed to the condensation of intermediates on the active sites and the partly aggregate of Pd.
