Abstract: With hydrogen peroxide as oxidant, we got a high selectivity of 2-hydroxy-1,4- naphthaqinone from 1- and 2-naphthol in methanol solution containing sodium hydroxide at low temperature. A series of tetraphenylporphyrin ferron chloride and its corresponding substitutes are employed as catalysts. By determination of UV-Vis and EPR spectra in situ, a probable mechanism model was established.

Key words: Catalysis mechanism of metalloporphyrin, Naphthol, 2-Hydroxy-1,4-naphthaqinone
