Research progress in the preparation of naphthoquinone by air-catalytic oxidation

air-catalyzed oxidation;  naphthalene;  Naphthoquinone

The methods of preparing naphthalequinone abroad (including liquid phase oxidation method and air catalytic oxidation method of naphthalene) were briefly introduced, and the research progress of 1,4-naphthoquinone preparation by naphthalene air catalytic oxidation was introduced. The advantages and disadvantages of various methods are compared, and the necessity and significance of domestic research and development of gas-phase catalytic oxidation to prepare naphthoquinone are demonstrated, which provides a reference for the research and development of naphthoquinone production and its production technology in China. At the same time, the study of naphthalene aerocatalytic oxidation can also provide a valuable reference for the development of catalysis science and catalytic technology.
