| Abstract: | Hydroxy 1,4 naphtholquinone(HNQ) was prepared in alcoholic solution of NaOH with high conversion and selectivity from both 1 naphthol and 2 naphthol in the presence of metalloporphyrin catalyst. An oxygen iron porphyrin was observed from UV Vis spectra when hydrogen peroxide was present in the catalytic system. The formation constants of the iron porphyrin intermediate were measured from its varying spectrum. The reactions of the formation and dissocination of HNQ are both of first order based on the relationship between HNQ concentration and reation time. |

| Keywords: | iron porphyrin catalys intermediate naphthol hydroxynaphthoquinone equilibrium constant |
