摘要：

We report on the synthesis of Menadione (vitamin K-3) by selective oxidation of 2-methylnaphthalene (2MN) with hydrogen peroxide over Ti- and Fe-containing catalysts. Different parameters affecting the oxidation of 2-methylnaphthalene with hydrogen peroxide on zeolite Fe-Beta are described. The influence of-the amount of catalyst as well as the concentration of hydrogen peroxide and the influence of the reaction temperature on the reaction rate were studied. The effect of the nature of the solvent was also investigated. All tests were performed over several selective oxidation zeolitic catalysts, synthesized and characterized in our laboratory.
