The ceria-supported rhenium catalyst modified with palladium (ReOx-Pd/CeO2 (Re = 2 wt %, Pd/Re = 0.25)) is still the best catalyst for simultaneous hydrodeoxygenation. Higher Re loading amount decreased the activity. The simultaneous hydrodeoxygenation of cyclic vicinal diols occurs with high cis-stereoselectivity. ReOx-Pd/CeO2 catalysts were characterized by means of XRD, TEM, H2-TPR, XAFS, XPS, Raman, and DFT calculations. The Re species on ReOx-Pd/CeO2 (Re = 2 wt %, Pd/Re = 0.25) catalyst after reduction and after stoichiometric reaction of 1,2-hexanediol to 1-hexene were ReIV and ReVI, and the ReIV species were converted to ReVI through the stoichiometric reaction. The Re species on ReOx-Pd/CeO2 are proposed to be randomly located on the CeO2 surface, and probably only monomeric Re species have catalytic activity for simultaneous hydrodeoxygenation. This model can explain the higher activity of Re = 2 wt % catalyst than those of higher Re loading catalysts. The reaction is proposed to proceed by the tetra/hexavalent redox cycle of the Re center in the catalysis followed by hydrogenation.

Azido polymers have been investigated as energetic binders in the area of solid rocket propellants. However, the low temperature mechanical properties of them are not comparable with the traditional propellant binders. In this work, a new kind of azido binder named poly (glycidyl azide-r-3-azidotetrahydrofuran) (PGAAT) was successfully synthesized. The molecular structures of monomers and copolymers were characterized. The sensitivity and thermal properties of the azido binder were studied. The cationic copolymerization of 3-methylsulfonyloxytetrahydrofuran with ternary cyclic ethers was confirmed. The PGAAT azido binder exhibited attractive features like low glass transition temperature (Tg, ?60 C) and high energy (1798 J/g). The results indicate that the polymer is a suitable candidate binder for the solid rocket propellants.

He I, UV photoelectron data and results from self-consistent-field (SCF) and post-SCF molecular orbital calculations were used to evaluate multiple gas-phase ionization potentials (IPs) of the phosphorylated dinucleotide 5?pGpAp both isolated and in a cluster with Na+ and H2O. SCF calculations with a split-valence basis set indicate that the ground-state valence orbital structure of 5?pGpAp is generally localized on the base, sugar, or phosphate groups and that orbitals in the dinucleotide are similar to orbitals in the model compounds and anion, 1,9-dimethylguanine, 9-methyladenine, 3-hydroxytetrahydrofuran, and H2PO4-. This correlation parallels that in mononucleotides (Fernando, H.; Papadantonakis, G. A.; Kim, N. S.; LeBreton, P. R. Proc. Natl. Acad. Sci. U.S.A. 1998, 95, 5550-5555; Kim, N. S.; LeBreton, P. R. J. Am. Chem. Soc. 1996, 118, 3694-3707) and permits the correction of SCF ionization potentials using experimental IPs for the model compounds and theoretical IPs from post-SCF calculations on H2PO4-. A comparison of IPs of 5?pGpAp, 5?pGpA, 2?-deoxyguanosine 5?-phosphate (5?-dGMP-), and 2?-deoxyadenosine 5?-phosphate (5?-dAMP-), both isolated and in gas-phase clusters with Na+ and H2O, indicates that the electrostatic influence of Na+ and the anionic phosphate groups is great. IPs decrease significantly as the number of phosphate groups increases. For 5?-dGMP-, 5?pGpA, and 5?pGpAp, the lowest adiabatic guanine ionization potentials are 5.2, 3.1, and 1.6 eV, respectively; the lowest phosphate vertical IPs are 5.1, 3.1, and 1.9 eV. Gas-phase IPs were combined with hydration energies obtained with a Langevin dipole relaxation model to evaluate the 22 lowest aqueous ionization energies in 5?pGpAp as well as ionization energies in the other nucleotides with and without counterions. The electrostatic dependence of the gas-phase IPs on the number of phosphate groups is modulated in aqueous solution. For 5?-dGMP-, 5?pGpA, and 5?pGpAp, the aqueous guanine and phosphate ionization energies lie in the ranges 4.2-4.9 eV and 5.5-6.1 eV, respectively. Solvent relaxation similarly modulates Na+ electrostatic effects. It also alters the relative energies of ionization events. In the gas phase, the first adiabatic base IP is equal to or larger than the lowest phosphate vertical IP. In water, the base ionization energies are 1.2-1.3 eV smaller than the phosphate ionization energies. Guanine gas-phase pi ionization energies in five different B-DNA oligomer models, each containing six stacked base pairs, were compared with site-specific reactivity data for methylation at the guanine N7 and O6 atoms by the carcinogen, N-methyl-N-nitrosourea (MNU). O6 methylation is associated with MNU carcinogenesis; N7 methylation is the principal DNA reaction pathway. At both guanine atoms, reactivity increases as the lowest guanine pi ionization potential decreases. This is consistent with a description of transition states in which activation barriers are lowered as nucleotide base pi polarizability increases.

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.category: Tetrahydrofurans, you can also check out more blogs about453-20-3

Wood pellets were pyrolyzed using a microwave oven and different microwave power, apparatus set-up and microwave absorbers (none, Fe, and carbon). Pyrolysis was realized in a short time in the presence of Fe or carbon while it was incomplete if the absorber was not present. Furthermore when the absorber was present the shape of the pellets remained unaltered while if the absorber was not employed pellets were disaggregated. Three fractions were collected from each pyrolysis: a gas, a liquid also called bio-oil and a solid called bio-char. The bio-oil contained two phases and they were quantitatively characterized through a GC/MS-FID procedure using an internal standard according to a previously reported method. HPLC/MS, FTIR and1H NMR spectroscopy were also employed for characterization of these liquids. Cellulose pyrolysis products were present in the upper phase such as water, acetic acid, furans (such as furfural), carbohydrates and their derivatives. Compounds from pyrolysis of lignin such as phenols and veratric acid were present in the bottom phase. The microwave assisted pyrolysis showed the possibility to efficiently convert wood pellets in different products. The main economical important components may be separated and used as chemicals, natural drugs or pesticides, while the remaining components, the solid and the gas may be used for energy production (solid and bio-oil). Solid may be also used for carbon sequestration.
