Transformation of certain organic compounds on exhaustive oxidation catalysts
The authors studied the role of water in vapor-phase catalytic oxidation. Two catalysts and three organic compounds of different chemical natures - formic acid, 4,4-dimethyl-1,3-dioxane, and isopropanol - were used as examples, and it was shown that water vapor does not hinder the vapor-phase transformations of these compounds at the intermediate stages of exhaustive catalytic oxidation during dehydrogenation and dehydration. It is assumed that the anomalous behavior of water, which, according to general kinetic regularities, hinders dehydration, is due to the activation of the catalyst by water vapor that oxidizes the reduced inactive forms to the active forms of the oxide. As a result, water has no negative influence on exhaustive oxidation, and the method of vapor-phase catalytic oxidation can be used for the purification of industrial vapor-gas effluents and wastewaters with parameters accepted in the purification of dry gases.
