Liquid Phase Oxidation of Cyclopentane with Nitrogen Dioxide.

Kinetics of Oxidation of Aqueous Sulfur(iv) by Nitrogen Dioxide

Although it is generally recognized that SOz and NOx (s NO + NOz) are the precursors of the strong acids (i.e., HzS04 and HN03) found in precipitation,! the detailed mechanisms for the oxidation of these compounds and their incorporation into atmospheric liquid water are not fully understood. In principle, the incorporation of acids into cloudor rainwater can take either or both of two pathways...

Nitrogen Dioxide Absorption and Sulfide Oxidation in Aqueous Sulfide.

Rates of nitrogen dioxide (NO2) absorption and sulfide oxidation were measured in a highly characterized stirred cell contactor at 55 °C, with O2 present in the gas phase. The rate constant of the reaction between NO2 and sul-fide at 55 °C was determined to be 26.4 x105 M-1sec-1. A reaction mechanism was proposed that is consistent with the kinetic data. NO2 absorption initiates sulfide oxidati...

Kinetic Studies of the Catalytic Oxidation of Toluene to Benzoic Acid in the Liquid Phase

The catalytic oxidation of toluene to benzoic acid in the liquid phase has been studied in an un-stirred tank reactor. Low concentration of acetic acid was added in order to increase the solubility of the catalyst in toluene. The dependence of the rate of reaction on the concentration of toluene catalyst and oxygen pressure was studied. It has been suggested that liquid phase oxidation of t...

Capacitive gas-phase detection in liquid nitrogen

The main and upper stages of heavy lift launchers for space applications are often fuelled by cryogenic liquids. In order to enable the re-ignition of a cryogenic upper stage for orbital changes, it is crucial to study the behaviour of these fluids in microgravity. As gaseous bubbles entering the fuel lines of the engine can cause the destruction of the engine, these bubbles are a risk for the ...
