Temperature dependence of the cathodic and anodic kinetics in a copper electrowinning cell based on reactive electrodialysis
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-09)
The temperature dependence of various kinetic parameters for the copper electrodeposition reaction and for the ferrous to ferric ion oxidation has been experimentally determined. Potentiodynamic sweeps were carried out in ...
Search for reaction pathways with P-graphs and reaction blocks: methanation of carbon dioxide with hydrogen
(Springer International Publishing, 2018)
The effects of carbon dioxide in the atmosphere can be reduced by closing
anthropogenic cycles, and the methanation of carbon dioxide with hydrogen provides
a promising option. Nevertheless, the reaction mechanism of ...
Oxidation of 3,5-ditert-butylcatechol catalyzed by copper(II) complexes. A kinetic study
(Elsevier Ltd, 1997)
Copper(II) complexes of the ligands (6-methyl-2,2′-dipyridyl)methane (MeDPM) and (6,6′-dimethyl-2,2′-dipyridyl)methane (diMeDPM) were prepared and used as catalysts for the oxidation of 3,5-ditert-butylcatechol to ...
Changes in the SNAr reaction mechanism brought about by preferential solvation
(Royal Soc Chemistry, 2015)
We herein report an experimental and theoretical study on preferential solvation effects for the reactions of 1-fluoro and 1-chloro-2,4-dinitrobenzene towards morpholine in acetonitrile, water and mixtures of them of varying ...
Unraveling the selectivity patterns in phosphine-catalyzed annulations of azomethine imines and allenoates
(American Chemical Society, 2020)
The mechanism and selectivity of phosphine-catalyzed [3 + 2] and [3 + 3] annulations of azomethine imines and allenoates have been computationally studied. Exploration of the potential energy surface reveals that the ...
Copper Electrodeposition Kinetics Measured by Alternating Current Voltammetry and the Role of Ferrous Species
(Electrochemical Soc, 2016)
Impurities and additives play a key role in copper electrodeposition, in particular in upstream processes such as electrowinning or electrorefining. One common impurity is iron, mostly present as iron species Fe(II) in ...
Effect of the nature of the nucleophile and solvent on an SNAr reaction
(Royal Society of Chemistry, 2018)
The reaction of 2,4-dinitrobenzenesulfonyl chloride toward propylamine was kinetically evaluated in 19 organic solvents and 10 ionic liquids as reaction media. This study was compared with a previous study to experimentally ...
Gutmann's Donor Numbers Correctly Assess the Effect of the Solvent on the Kinetics of SNAr Reactions in Ionic Liquids
(2016)
We report an experimental study on the effect of solvents on the model SNAr reaction between 1-chloro-2,4dinitrobenzene and morpholine in a series of pure ionic liquids (IL). A significant catalytic effect is observed with ...
Reaction of singlet molecular oxygen, O2(1 Δg), with the Cinchona tree alkaloids: Effect of absolute configuration on the total rate constant
(2005)
Detection of O2(1Δg) emission, λmax = 1270 nm, following laser excitation and steady-state methods were employed to measure the total reaction rate constant, kT, and the reactive reaction rate constant, kR, for the reaction ...
