Nitric Acid Oxidation of 4-Methylcyclohexene

Atomistic oxidation mechanism of a carbon nanotube in nitric acid.

Motivated by recent experiments, we investigate how NO3-SWNT interactions become energetically favorable with varying oxidation state of a single-walled carbon nanotube (SWNT) using first-principles calculations. Chemisorption becomes less endothermic with respect to physisorption when the SWNT oxidation state is elevated. Importantly, the dissociative incorporation of an oxygen atom into the S...

Modifications in the nitric acid oxidation of D-glucose.

The nitric acid oxidation of D-glucose was reinvestigated in an effort to better understand and improve the oxidation and subsequent work up steps. The oxidation was carried out using a computer controlled reactor employing a closed reaction flask under an atmosphere of oxygen which allowed for a catalytic oxidation process with oxygen as the terminal oxidant. Removal of nitric acid from produc...

Kinetics of oxidation of pentavalent neptunium by pentavalent vanadium in solutions of nitric acid

The behaviors of reduction of NpO2 by controlled potential electrolysis were studied, and a unique time course of electrolysis current was observed. It was concluded that NpO2 was reduced by two reduction processes, which were the chemical reaction with Np and the electrocatalytic reduction by adsorbed hydrogen atom on platinum electrode surface. The time courses of current for controlled poten...

Catalytic Oxidation of 4-Methylpyridine on Modified Vanadium Oxide Catalysts

The reaction of gas-phase oxidation of 4-methylpyridine on individual V2O5, binary and ternary vanadium-oxide catalysts was studied. These catalysts were modified by additives of SnO2 and TiO2. It was found that modifying V2O5 leads to increase the activity of binary contacts. Upon transition from binary V2O5<...
