To absolute acetonitrile (1950 mL) degassed via three vacuum/nitrogen ingress cycle wasadded dichloropalladium (13 g, 73 mmol), the mixture was refluxed at 90~100 °C overnight.The reactant was concentrated to obtain Pd(CH3CN)2Cl2 as orange solid. To a suspension ofPd(CH3CN)2Cl2 (19 g...
The growth in catalytic current anodic of the\({E}_{{{\rm{Ni}}}^{{{\rm{II}}}/{{{\rm{I}}}\)potential suggests the involvement of NiIin the hydrogen evolution reaction. To probe the process chemically, CoCp*2was chosen as a reductant for an EPR-scale reduction of1at −35 °...
Formyl radicals can convert to CO by losing hydrogen in two ways (Fig.4a). Firstly, it can lose an H atom directly (R25). Figure4bshows a real-time trajectory of this process. A formyl radical lost its H atom at about 405.79 ps, but this reaction was quickly reversed and the fo...
The decomposition of electromagnetic radiation into its component wavelengths is fundamental to spectroscopy. Evolving from the first crude prism spectrographs that separated white light into its constituent colours, modern spectrometers have provided ever-increasing wavelength resolution. Large-grating spectromet...
Reaction network 1. Introduction Simply defined design tasks, such as synthesis planning [1], [2], often involve a large number of choices. In the present paper, we address a problem of formulating a large system of ordinary differential equations (ODEs) that implements autoxidation reaction kine...
Reaction between N2O and CH4 over Fe ion-exchanged BEA zeolite catalyst: A possible role of nascent oxygen transients from N2O above 200°C, while both the O2+CH4 reaction and the catalytic decomposition of N2O over the Fe-BEA catalyst required higher temperatures (above 400°C... S Kameoka...

The outlet of the reactor is connected to the inlet of a water column, whereas the outlet of the column is directed to a beaker that is placed on a digital balance (BB-1550, MRC) that monitors the weight change as a function of time during the decomposition reaction. Before the start ...
