Effect of Ag-Co interactions in the mordenite on the NO x SCR with butane and toluene
(Elsevier Science, 2012-11)
A study of the lean NO x reduction activity with butane and toluene in the presence of water over bimetallic and monometallic Ag, Co exchanged on Na-mordenite catalysts was performed. The Ag-Co interactions were analyzed ...
Oxidation of gold nanoparticles by Au(III) complexes in toluene
(American Chemical Society, 2012-07-22)
The rapid, stoichiometric oxidation of gold nanoparticles by tetraalkylammonium and tetraalkylphosphonium Au(III) complexes in toluene is reported here. Nanoparticle oxidation proceeds via a comproportionation mechanism ...
Geometries and Interaction Energies of Toluene on CsxNa1–xMordenite
(Wiley VCH Verlag, 2020-06)
Calculations of the geometries and energies of the alkaline mordenites (MOR) CsxNa1–xMOR (where x = 0, 0.25, 0.5, 0.75, and 1) with and without toluene are reported. Differential scanning calorimetry (DSC) experiments are ...
Novel (NH4)4[NiMo6O24H6]·5H2O – TiO2 composite system: Photo-oxidation of toluene under UV and sunlight-type illumination
(Elsevier Science, 2018-12-20)
A series of composite materials based on titania and growing quantities of the (NH4)4[NiMo6O24H6]·5H2O heteropolyacid (NiMo6 HPA) was tested in the gas-phase toluene photo-oxidation reaction. Materials were characterized ...
Thermal effects on the electric deflection of toluene molecules
(Elsevier Science, 2008-12)
A series of precise electric deflection experiments were done on a supersonic beam of toluene molecules in several expansion conditions and field strengths. We analyzed the effect of a gradual rotational cooling on the ...
Influence of temperature on liquid - liquid equilibrium of methanol + toluene + hexane ternary system at atmospheric pressure
(Springer/Plenum Publishers, 2018-09)
Abstract Liquid-liquid equilibrium of methanol + toluene+ hexane ternary system at 278.15,283.15, 288.15 and 293.15 K are reported. The effect of the temperature on liquid-liquidequilibrium is discussed. All chemicals were ...
Effect of titanium-doping on the properties of vanadium antimonate catalysts
(Elsevier Science, 2000-02)
Catalysts of nominal compositions VSb1 - xTixO4, with x = 0, 0.1, 0.2 and 0.4, were prepared by solid state reaction of vanadium(V) oxide, antimony(III) oxide and titanium(IV) oxide mixtures. Their structural and catalytic ...
Stability and activity of Zn/MCM-41 materials in toluene alkylation: Microwave irradiation vs continuous flow
(MDPI, 2019-02-01)
Zn/MCM-41 mesoporous materials have been prepared via classic wet impregnation, employing zinc nitrate as precursor and tested for activity and stability in the Friedel-Crafts alkylation of toluene with benzyl chloride ...
Hybrid separation and detection device for analysis of benzene, toluene, ethylbenzene, and xylenes in complex samples
(American Chemical Society, 2009-11)
We present a hybrid system for rapid detection and analysis of benzene, toluene, ethylbenzene, and xylenes (BTEX). The system combines selective and sensitive sensing elements with a fast and miniaturized chromatographic ...
