The kinetics of the oxidn. of nitrite to nitrate by peroxynitrous acid at pH 5.2 is best described by the rate law kobs = kiso + k'[NO2-] + k''[NO2-]2, in which the peroxynitrous acid isomerization rate const. kiso = (1.10 +- 0.05) s-1, k' = (3.2 +- 0.1) M ...
This study focuses on an interesting and important phenomenon that was employed in a new approach to laser isotope separation that has been recently proposed and developed in our laboratory for highly selective separation of carbon isotopes. This approach ...
The ruthenium(II) hexaaqua complex [Ru(H2O)6]2+ reacts with dihydrogen under pressure to give the h2-dihydrogen ruthenium(II) pentaaqua complex [Ru(H2)(H2O)5]2+.The complex was characterized by 1H, 2H and 17O NMR: d H = -7.65 ppm, J HD = 31.2 Hz, d O = -80 ...
The effect of pressure on the Diels-Alder reaction was examined in room temperature ionic liquids, followed by high-pressure FT-IR spectroscopy using pressures up to 150 MPa. Pressure enhances the kinetic sensitivity of the reaction. The kinetic effec ...
The kinetics of chlorination of several phenolic compounds and the corresponding formation of chloroform were investigated at room temperature. For the chlorination of phenolic compounds, second-order kinetics was observed, first-order in chlorine, and fir ...
We report in this paper on the electrochemical formation of nickel tetrasulfonated phthalocyanine (NiTSPc) based films on bulk Pt disk microelectrodes (diameter d = 50 μm) and thin-film Pt microdisk (diameter d = 10 μm) arrays for the realisation of Pt bas ...
Accelerated bleaching, photobleaching and mineralization of the non-biodegradable azo-dye, Orange II, was obsd. with oxone in solns. with Co2+-ions. The bleaching rate of Orange II in the dark was found to follow a first-order kinetics with respect to [Co2 ...
The present thesis work deals with the investigation of the heterogeneous reactions involving nitrate radical (NO3), dinitrogen pentoxide (N2O5) and ozone (O3) on surrogates of atmospheric mineral dust particles characteristic of the troposphere. An additi ...
The water-sol. ruthenium(II) complexes [Cp'RuX(PTA)2]Y and [CpRuCl(PPh3)(mPTA)]OTf (Cp' = Cp, Cp*, X = Cl and Y = nil; or X = MeCN and Y = PF6; PTA = 1,3,5-triaza-7-phosphaadamantane; mPTA = 1-methyl-1,3,5-triaza-7-phosphaadamantane) were used as catalyst ...
