Abstract

2-Hydroxy-1.4-naphthaquinone (HNQ) was selectively synthesized from catalytic oxidation of 2-naphthol by molecular oxygen over tetra(4-methoxyl-phenyl)porphyrinate iron(III) chloride (TMOPPFeCl) catalyst in an alkali methanol solution under mild conditions. The influences of solvents, temperature, time, as well as amounts of catalysts and alkali were studied. The quantitative data show that 32.9% of 2-naphthol (0.093 mol/dm3) was catalytically converted to HNQ with the selectivity of 100% at 323 K for 9 h over TMOPPFeCl catalyst (2.54→10−4 mol/dm3) in alkali media (30 mL of methanol containing 2.5 mol/dm3 of NaOH) by flowing molecular oxygen (flowing rate of 45 mL/min).
