General description
2-Methyl-1-naphthol undergoes oxidation with molecular oxygen to yield 2-methyl-1,4-naphthoquinone. Mechanism of selective oxidation of 2-methyl-1-naphthol with H2O2 catalyzed by titanium single-site catalysts, TiO2-SiO2 aerogel and mesostructured hydrothermally stable titanium-silicate has been investigated by EPR spectroscopic technique.
Application
2-Methyl-1-naphthol was used in selective synthesis of vitamin K3 via liquid-phase oxidation using NbSBA-15 catalyst.

Oxidation of 2-methyl-1-naphthol (MNL) with molecular oxygen proceeds efficiently under mild reaction conditions (3 atm O(2), 60-80 °C) in the absence of any catalyst or sensitizer and produces 2-methyl-1,4-naphthoquinone (MNQ, menadione, or vitamin K(3)) with selectivity up to 80% in

Well hexagonally ordered NbSBA-15 catalysts synthesized by an efficient hydrothermal method were used, for the first time, for the selective synthesis of vitamin K(3) by liquid-phase oxidation of 2-methyl-1-naphthol (2MN1-OH) under various reaction conditions. The recyclable NbSBA-15 catalysts were also
