The oxidation of phenol on the surface of silica gel
Russian Journal of Physical Chemistry A
The possibility of oxidizing phenol at room temperature in air by bringing it in contact with silica gel was demonstrated. The rate of the process was determined by the phenol/silica gel ratio and the intensity of supplying oxygen into the system. Phenol was oxidized to benzoquinones in sulfuric acid in the presence of silica gel. The results are preliminarily explained on the assumption of the formation of the high-reactivity singlet oxygen form 1Δg on the surface of silica.
