Preparation of 2-Hydroxyl-1,4-naphthoquinone by Catalytic Oxidation of Naphthol over Iron Porphyrin
Abstract:
The 2-hydroxyl-1, 4-naphthoquinone(HNQ) was prepeared by catalytic oxidation of 1-naphthol and/or 2-naphthol in NaOH methanol solution with H2O2 over 5,10,15,20 tetra(4-methoxyl)phenyl porphyrin iron chloride in yield of 57% and purity of 95%. The UV-Vis, IR, NMR, MS, mp determination and elemental analysis were used for characterization. A spectro photometric method was proposed for quantitative analysis of HNQ using λmax=452 nm.
