Biomass-derived 5-hydroxymethylfurfural (HMF) is hailed as an all-purposed platform molecule that holds great promise to address a number of high volume markets for chemicals, polymeric materials, and transportation fuels. HMF-derived diols, including 2,5-bishydroxymethylfuran (BHMF), 2,5-bishydroxymethyltetrahydrofuran (BHMTF), and 1,6-hexanediol (1,6-HD), are key intermediates for the catalytic upgrading of HMF in a biorefinery. These diols can be employed as renewable polymeric monomers, and among them BHMF and BHMTF are also attractive precursors for biofuels, such as 2,5-dimethylfuran (DMF), 2,5-bis(alkoxymethyl)furans (BAMFs), and 2,5-dimethyltetrahydrofuran (DMTHF). Hence, gaining more insights into the chemoseletive hydrogenation of HMF to these diols is of particular importance. In this review, we comprehensively summarize the advances in the selective hydrogenation of HMF into these diols in terms of the diversity of hydrogen sources, mainly including molecular H2, alcohols, formic acid and water, over homogeneous or heterogeneous catalysts. Assessment of the relative merits of different hydrogen sources for the hydrogenation of HMF is performed as well. We also discuss challenges and opportunities in employing these HMF-derived diols for the production of polymeric materials and biofuels.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of (cis-Tetrahydrofuran-2,5-diyl)dimethanol, you can also check out more blogs about2144-40-3

Reference of 7175-81-7, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 7175-81-7, Name is (S)-(Tetrahydrofuran-2-yl)methanamine,introducing its new discovery.

To search for TNF-alpha (tumor necrosis factor alpha) converting enzyme (TACE) inhibitors, we designed a new class of macrocyclic hydroxamic acids by linking the P1 and P2? residues of acyclic anti-succinate-based hydroxamic acids. A variety of residues including amide, carbamate, alkyl, sulfonamido, Boc-amino, and amino were found to be suitable P1 P1-P2? linkers. With an N-methylamide at P3?, the 13-16-membered macrocycles prepared exhibited low micromolar activities in the inhibition of TNF-alpha release from LPS-stimulated human whole blood. Further elaboration in the P3?-P4? area using the cyclophane and cyclic carbamate templates led to the identification of a number of potent analogues with IC50 values of ?0.2 muM in whole blood assay (WBA). Although the P3? area can accommodate a broad array of structurally diversified functional groups including polar residues, hydrophobic residues, and amino and carboxylic acid moieties, in both the cyclophane series and the cyclic carbamate series, a glycine residue at P3? was identified as a critical structural component to achieve both good in vitro potency and good oral activity. With a glycine residue at P3?, an N-methylamide at P4? provided the best cyclophane analogue, SL422 (WBA IC50 = 0.22 muM, LPS-mouse ED50 = 15 mg/kg, po), whereas a morpholinylamide at P4? afforded the most potent and most orally active cyclic carbamate analogue, SP057 (WBAIC50 = 0.067 muM, LPS-mouse ED50 = 2.3 mg/kg, po). Further profiling for SL422 and SP057 showed that these macrocyclic compounds are potent TACE inhibitors, with Ki values of 12 and 4.2 nM in the porcine TACE assay, and are broad-spectrum MMP inhibitors. Pharmacokinetic studies in beagle dogs revealed that SL422 and SP057 are orally bioavailable, with oral bioavailabilities of 11% and 23%, respectively.

Electric Literature of 4100-80-5, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 4100-80-5, 3-Methyldihydrofuran-2,5-dione, introducing its new discovery.

Few investigations have been made to apply thermal analysis methods on solid residue analysis to understand biomass liquefaction mechanistic information. To investigate the mechanism of cornstalk liquefaction in water/ethanol mixtures, the solid residues remaining after the liquefaction process were characterized by thermogravimetric analysis (TGA) and analytical pyrolysis (Py-GC/MS). Pyrolysis temperature and liquefaction temperature have synergetic effects on the distributions and yields of various chemical groups during the pyrolysis process. The thermal stabilities of the solid residues remaining after the cornstalk liquefaction process increased with the increase of liquefaction temperature. Compared with raw cornstalk pyrolysis, the proportions of total phenol compounds from solid residue pyrolysis at 400 C, 500 C and 600 C were reduced. The volatilized compounds identified by Py-GC/MS analysis of solid residues and cornstalks displayed significant variability in the peak area and composition distribution. These changes reflect different mechanistic information during the biomass liquefaction process. These results indicate that analytical pyrolysis of the solid residues remaining after biomass liquefaction in water/ethanol mixtures could provide new information about the mechanism of the liquefaction process.
