Vapor phase catalytic oxidation and/or ammoxidation of cyclohexanone and/or cyclohexanol to phenol and/or aniline

摘要

Cyclohexanone and/or cyclohexanol can be oxidized in the vapor phase to phenol by contacting the cyclohexanone and/or cyclohexanol with a suitable oxidation catalyst in the presence of molecular oxygen. Suitable catalysts are solids comprising Mo, W, Sb and/or V oxides or complexes thereof. The catalysts may be promoted with additional elements.
