Liquid Phase Oxidation of 2,6-Di-t-butylphenol by Molecular Oxygen Using Magnesium Oxide Catalysts Modified with Metal Ion

Article abstract of DOI:10.1246/cl.1987.1919

Mn(II), Co(II), Cu(II), or Fe(III) ion containing magnesium oxides catalyzed oxidation of 2,6-di-t-butylphenol to quinones by molecular oxygen. 98percent Yield to 1,1'-bis(4-oxo-3,5-di-t-butylcyclohexadienylidene) was obtained with 16.7 wtpercent Mn ion containing magnesium oxide catalyst.
