The kinetic of the oxidation of InSn48

Analytical and Bioanalytical Chemistry, 1995
The oxidation of InSn48 has been investigated at partial pressures between 10(-8) Pa and 10(+4) Pa over a temperature range from 22 ( degrees )C to 250 ( degrees )C with different analytical methods. The oxide film contains a mixture of several oxides, although indium oxide forms preferentially.

Oxidation and Decomposition Kinetics of Thiourea Oxides

The Journal of Physical Chemistry A, 2007
In this report the decomposition and oxidation kinetics of thiourea dioxide and thiourea trioxide are investigated with a reversed-phase ion-pair high-performance liquid chromatography (HPLC) method. The HPLC method allows us to simultaneously determine and quantify several sulfur-containing reagents such as (NH2)2CSO2, (NH2)2CSO3, (NH2)2CO, and SO3(2-)

Kinetics of the Oxidation of Triphenylphosphine by Nitric Oxide

Inorganic Chemistry, 2002
The oxidation of PPh3 by NO to N2O and Ph3PO in homogeneous solution occurs by third-order kinetics, d[Ph3P]/dt = k3[Ph3P][NO]2; analysis of solvent and substituent effects suggests formation of a phosphonium diazeniumdiolate intermediate prior to oxygen transfer from nitrogen to phosphorus.

KINETICS AND MODELING OF BENZENE OXIDATION

Chemical Engineering Communications, 1982
The gas phase oxidation of benzene over a V2O5 + P2O5 + MoO3 + Sb2O3 catalyst supported on kieselguhr carrier is studied at the temperature range 344–393°C. 14 different kinetic models are tried to determine the mechanism of benzene oxidation. It is shown that benzene oxidation takes place via a two step redox mechanism which is first order with ...

Kinetics of nitric oxide oxidation

Chemical Papers, 2010
AbstractNitrogen oxides are nowadays a subject of global concern. Several types of nitrogen oxides exist in the environment: N2O, NO, NO2, N2O3, N2O4, N2O5. The abbreviation NOx usually relates to nitric oxide NO, nitrogen dioxide NO2, and nitrous oxide N2O.

Kinetics of Diesel Nanoparticle Oxidation

Environmental Science & Technology, 2003
The technique of high-temperature oxidation tandem differential mobility analysis has been applied to the study of diesel nanoparticle oxidation. The oxidation rates in air of diesel nanoparticles sampled directly from the exhaust stream of a medium-duty diesel engine were measured over the temperature range of 800-1140 degrees C using online aerosol ...

Oxidative desulfurization: Kinetic modelling

Journal of Hazardous Materials, 2009
Increasing environmental legislations coupled with enhanced production of petroleum products demand, the deployment of novel technologies to remove organic sulfur efficiently. This work represents the kinetic modeling of ODS using H(2)O(2) over tungsten-containing layered double hydroxide (LDH) using the experimental data provided by Hulea et al.

VPO Transient Oxidation Kinetics

International Journal of Chemical Reactor Engineering, 2006
Transient and steady state reactor data for the partial oxidation of butane to maleic anhydride were collected in a fluid bed over DuPont commercial vanadium pyrophosphate catalyst (VPO) principally under butane rich, oxygen deficient operating conditions.
