Process for producing 2,6-dihydroxynaphthalene and 2,6- diacetoxynaphthalene

摘要

Disclosed herein is a process for producing 2,6- dihydroxynaphthalene which comprises oxidizing 2,6-di(2-hydroxy-2-propyl) naphthalene in acetonitrile, 1,4-dioxane or a mixture thereof with hydrogen peroxide in the presence of an inorganic acid or a solid acid at a temperture in the range of room temperature to the boiling point of the solution of the 2,6- di(2-hydroxy-2-propyl)naphthalene in acetonitrile or 1,4-dioxane, the acetonitrile, 1,4-dioxane or a mixture thereof being used in an amount of 3 to 30 ml to one gram of the 2,6-di(2-hydroxy-2- propyl)naphthalene.
