Upgrading pine sawdust pyrolysis oil to green biofuels by HDO over zinc-assisted Pd/C catalyst

Upgrading pyrolysis oil by hydrodeoxygenation (HDO) is a promising route for the production of advanced biofuels. The proper reaction conditions and catalysts are important for the success of this process. Previously our research group investigated the ratio of Zn and Pd on the synergistic effect for HDO bio-oil upgrading. This present research focuses on determining the optimal reaction conditions for HDO conversion of pyrolysis oil produced from pine sawdust. Temperatures of 150, 200 and 250C and hydrogen pressures of 1.38, 2.76 and 4.14 MPa were evaluated. Syngas, liquids and coke were the primary products evaluated. Syngas was characterized using a Gas chromatography (GC). The liquids were characterized using a Gas chromatography-mass spectrometry (GC-MS). Increasing reaction temperature resulted in increased coke yields. Treatment at 250C and 1.38 MPa resulted in the highest hydrocarbon content (6.06%). The treatment at 200C and 1.38 MPa produced the largest amounts of hydrocarbons in C6-C12 range (5.07%). The physicochemical characterizations further support the GCMS results. Syngas analysis revealed that higher hydrogen pressure leads to increased hydrogen consumption and results in more oxy-compounds conversion to hydrocarbons. The syngas analysis also supports the liquid analysis result.

Phosphorus pentoxide as an efficient catalyst for the tetrahydropyranylation of alcohols under solvent-free conditions

A facile and efficient method for the preparation of tetrahydropyranyl ethers from alcohols is improved in solvent-free media. These reactions are catalyzed by P2O5 and afford various tetrahydropyranyl ethers in shorter reaction time, with good to excellent yields (75-95%) at room temperature. This method is also compatible with substrates containing acid-sensitive functional groups.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 5631-96-9!, 5631-96-9

Selective Heck reaction of electron-rich aryl bromides with cyclic alkenones

A simple and efficient protocol for the Heck reaction of cyclic alkenones with electron-rich aryl bromides has been developed. A ligand combination of X-Phos and tri-tert-butylphosphonium hydrogen tetrafluoroborate in the presence of Pd(PPh3)2Cl2 and Na2CO3 in DMSO was found to be efficient and selective for electron-rich aryl bromides with high substrate scope for cyclic alkenones.

Complexes of copper(II) dihalide with 2,2?-dipyridylamine. X-ray diffraction structures of the [dibromo-bis(dipyam)copper(II)]-water (1:2) and di[chloro-bis(dipyam)copper(II)]diiodide-acetonitrile (1:2) complexes

The formation of complexes between copper(II) halides and 2,2?-dipyridylamine (dipyam) has been studied systematically. Only complexes with a 1:1 and 1:2 metal-to-ligand ratio are formed. Some mixed chloro-iodide and halide-PF6 compounds have also been isolated. The X-ray diffraction structures of the [Cu(dipyam)2Br2] ¡¤ 2H2O (I) and the [Cu(dipyam)2Cl]2I2 ¡¤ 2CH3CN (II) complexes are reported. I is a rare example of an octahedral coordination among the copper(II) halide complexes of dipyam. The two bromo atoms, which occupy the apical positions, are H-bonded to the water molecules of crystallization. II is a dimer, where each copper forms a cationic chloro-complex of approximately trigonal bipyramidal geometry, the dimerization being due to hydrogen bonds formed by the NH group of one of the two dipyams coordinated to each metal atom with the chlorine atom of the centrosymmetric cationic complex. The iodide anions are hydrogen-bonded to the NH groups of the dipyams not involved in the dimerization.

17alpha- and 17beta-boldenone 17-glucuronides: Synthesis and complete characterization by 1H and 13C NMR

Boldenone is an androgenic anabolic steroid intensively used for growth promoting purposes in animals destined for meat production and as a performance enhancer in athletics. Therefore its use is officially banned either in animals intended for consumption or in humans. Because most anabolic steroids are completely metabolized and usually no parent steroid is excreted, metabolite identification is crucial to detect the illegal use of anabolic steroids either in humans or in livestock. 17alpha- and 17beta-boldenone 17-glucuronides were synthesized, purified and characterized in order to provide suitable standards for the identification and quantification of these metabolites.

The synthesis and structure characterization of inorganic/organic coordination polymers was demonstrated. The hydrothermal synthesis of the polymers using microwave heating was used as a synthetic tool to reduce the reaction and crystallization time. X-ray crystallography was used to characterize the molecular structure of the polymers. The analysis of x-ray powder diffraction data suggested the structural influence of organic component and the geometrical preference of metal centers.
