A new donor-acceptor polymer poly (3-Cyanopyridine-fluorene) (PCP) was designed, and synthesized by using Suzuki coupling reaction. The synthesized polymer, PCP hybridized TiO2 nanocomposites were prepared from the blends of TiO2/PCP by varying the PCP percentage (0.3–0.6 wt%). Presence of poly...

The self-assembly of monolayers of benzyl mercaptan (benzenemethanethiol, C6H5CH2SH) on Au(1 1 1) at room temperature has been studied by low energy electron diffraction and high resolution electron energy loss spectroscopy (EELS). It was found that the orientation of the molecule depends on cov...

Ortho- and meta-nitrobenzaldehydes are two important intermediates in the chemical industry. They are the main products of benzaldehyde nitration by mixed acid, which is a hazardous chemical process since reaction rates are very sensitive to variations of the operating conditions. In the present...

Selective production of aromatic aldehydes is an important challenge in the synthesis of fine chemicals. This study presents a viable strategy for the production of benzaldehyde using a magnetic recoverable photocatalyst. Graphitic carbon nitride was submitted to a thermal post-treatment, for pa...

Soil fungistasis limits the effect of fungal agents designed to control plant-parasitic nematodes. Benzaldehyde is a fungistatic factor produced by soil microorganisms that can suppress conidial germination, but the molecular mechanism of this suppression is unknown. In this study, three conidia...

To resolve the defects of acetic acid solvents for the liquid-phase oxidation of toluene to benzaldehyde with oxygen, a low-corrosive and green method was developed by introducing benzyl benzoate into the reaction. It was found that compared with the case of acetic acid, benzyl benzoate showed g...

Synthesis of benzyl methyl ether from benzyl alcohol and methanol in high-temperature carbonic water was studied in a batch reactor. Benzyl methyl ether formation was not observed by reacting benzyl alcohol with only methanol under supercritical conditions at 573 K. On the other hand, benzyl met...

Copper-based coordination polymers, Cu2(μ2-MeCO2)4(DABCO) (1), [Cu(1,4-BDC-Br)(DABCO)0.5]. xDMF.yH2O (2) and Cu(1,4-BDC-OH)(DMF) (3) (1,4-BDC-Br = 2-bromoterephthalate, DABCO = triethylenediamine, 1,4-BDC-OH = 2-hydroxyterephthalate) were solvothermally synthesized. Two polymorphs of 1 (1a and ...

We prepared a high-concentration suspension of boron nitride (BN) nanoplates stabilized with benzyl alcohol (B-BN) in epoxy resin as a polymer composite adhesive for a highly efficient heat dissipation. At a BN concentration of 40 wt%, the polymer composite with B-BN exhibited a high thermal con...

A series of MeOx/sepiolite (Me = Cu, Cr, Mn, Co, Ni) catalysts was prepared through the deposition–precipitation and characterized by means of XRD, EDS, SEM, BET, and H2-TPR. The structural characterization showed a fine distribution of MeOx metal oxides on magnesium silicate nanobars. The sepi...

Graphitic carbon nitride (CN) enriched with ZnO or Fe2O3 were synthesized using a simple one-pot mechanochemical method. By using this method, composite samples were synthetized without the production of any potentially hazardous waste. Synthesized materials were used as catalysts during selecti...

A series of CuCeO2catalytic materials, with copper loadings in the 5–20 wt% range, was prepared, characterized and tested in the oxidation of benzyl alcohol to benzaldehyde in batch conditions, at 100 °C employing water as the solvent. Different CeO2and CuCeO2 samples were obtained following h...

The atmospheric oxidation of benzyl alcohol (A1CH2OH) has been investigated in a jet-stirred reactor (JSR) at equivalence ratios of 0.4 and 2.0 within 700–1100 K. Mole fraction profiles of 19 species were analyzed by online GC and GC/MS techniques. Rate constants of the unimolecular decompositi...

Due to the convenience of catalyst separation and solvent-free conditions, gas-phase oxidation of benzyl alcohol-in particular to-benzaldehyde reaction is more attractive method for industrial applications. In this respect it is environmentally and scientifically important to develop a low cost,...

A series of catalysts consisting of gold–palladium bimetallic nanoparticles (Au–Pd NPs in the range of 1–6 nm) anchored on foamlike mesoporous silica were used for the aerobic oxidation of benzyl alcohol. A remarkable synergistic effect was observed on these Au–Pd NP catalysts prepared by a ...

A liquid–liquid extraction equilibrium model was developed describing the extraction of aqueous 4-cyanopyridine with the reactive solvent 4-nonylphenol. The model describes the capacity of the solvent up to an equilibrium aqueous phase concentration of 20 g/L within a temperature interval of 25...
