The liquid-liquid coexistence curve in a temperature range of about 8 K from the upper consolute point and the specific isobaric heat capacity in a wide temperature range for the critical binary solution of {n-decane + benzonitrile} have been precisely measured. The upper consolute mole fraction...

The Pd/Al2O3 catalyst was prepared by the impregnation method to investigate the deactivation and mechanism of coke formation on metal catalysts for the selective hydrogenation of benzonitrile in a continuous fixed-bed reactor under mild conditions. The Pd/Al2O3 catalyst exhibited the initial be...

Highly-dispersed nickel-based catalysts (NiMgAlO-op) were prepared from NiMgAl layered double hydroxide precursors with various Ni/Mg/Al molar ratios via a one pot method. The obtained catalyst with a Ni:Mg:Al molar ratio of 1:0.75:0.25 was highly active and selective for benzylamine (90.6%) in ...

As a novel mushroom tyrosinase inhibitor, 4-methoxybenzonitrile (anisnitrile) was identified (IC50 = 111.1 μM) with hyperbolic inhibition manner. The calculated αKi (166.3 μM) was larger than Ki (66.5 μM) by Dixon plots, indicating that this nitrile acts as a competitive-noncompetitive mixed...

Overall water splitting represents one of the most promising approaches toward solar energy conversion and storage, which is, however, severely challenged by the four-electron/four-proton nature of the oxygen evolution reaction (OER). One option to overcome this issue is to replace OER with a mo...

Cyclohexane/cyclohexene separation is one of the most complex and relevant hydrocarbon separations due to the close boiling points of these two cyclic hydrocarbons and the relevance of both compounds in the petrochemical industry. The production of cyclohexane, cyclohexene, and benzene usually m...

Infrared and Raman spectra in the liquid state of 3-R, 4-X cyclohexenes (R = CH3, (CH3)3C; X = CN,Cl) and their d1-(4) and d3-(3,6,6) isotopic modifications, Raman spectra of some low temperature crystallised compounds, vibrational spectra in the solid state of cis and trans 1-acetoxy 3-t-butyl ...

The three component coupling reaction of aldehydes, phenylacetamide and dienophiles gave the corresponding N-phenylacetamidocyclohexene derivatives in good yields (55–70%) and high regioselectivity. For the first time, enzymatic kinetic resolution of this class of compounds has been achieved. T...

Infrared and Raman spectra of 4-cyano cyclohexenes d0 and d4-(3,3,6,6) and 4-methyl cyclohexene have been recorded in the liquid state and, for the two first products, in the crystalline state at low temperature. These experimental results and the effect of temperature on the Raman line intensit...

The stereochemistry of the methoxymercuration of 1-cyano-3-cyclohexene and trans-1,2-dicyano-4-cyclohexene has been studied by NMR spectroscopy using partially deuterated model compounds. The configuration of the methoxymercurials formed suggest that the previously postulated “specific directin...

A novel nonwoven fabric adsorbent having 4-vinylpyridine functional groups was prepared by using radiation-induced emulsion graft polymerization method and grafting 4-vinylpyridine monomer onto a polyethylene-coated polypropylene nonwoven fabric (NWF) in aqueous emulsion solution. The grafting c...

An interesting, electrical behavior of Poly(4-vinylpyridine) was observed at different pH values. 4-vinylpyridine was grafted onto mechanically durable poly(propylene) films to synthesize a pH responsive hydrogel. We have focused on the influence of temperature and pH on the electrical behavior ...

pH-responsive poly(4-vinylpyridine) (P4VP) grafted cellulose nanocrystals (P4VP-g-CNC) were prepared by Surface-Initiated Atom Transfer Radical Polymerization (SI-ATRP) and subsequently used to stabilize gold nanoparticles (Au NPs) as efficient and recyclable nanocatalysts for the reduction of 4...

A new green and simple method of synthesis of polymeric nanoparticles comprising a pH-responsive polymer and a sulfonated dye, without needing the use of any organic solvent or cross-linker, is shown. It is based on the complexation between weak basic aromatic polyelectrolytes and a strong acidi...

Poly(4-vinylpyridine-co-divinylbenzene) polyHIPE was prepared with 80% porosity and a typical cellular interconnected topology. Up to 25% of 4-vinylpyridine (VP) was introduced into polymer.
