In the traditional process,β-methylnaphthalene is oxidized with solution of chromic acid to give β-methylnaphthoquinone. However, a great deal of waste water with chromium will be produced in the process, which is very serious to environment. At the same time, the raw material consumption is great, which lead to the high production cost. Furthermore, by-product 6-methyl-1, 4-naphthoquinone will be produced, which is difficult to be separated completely and be utilized solely.
