PURPOSE: To obtain the titled compound in high yield without necessitating complicate operations, by oxidizing 2,6-di(2-hydroxy-2-propyl)nephthalene with hydrogen peroxide in a specific solvent such as acetonitrile in the presence of a strongly acidic cation exchange resin.
CONSTITUTION: The objective compound of formula II useful as a production raw material for liquid crystal polymer can be effectively produced in high yield without causing the separation difficultly and the problem of waste water treatment, by oxidizing 1mol of 2,6-di(2-hydroxy-2-propyl)naphthalene with preferably 2W3mol of hydrogen peroxide in the presence of 0.01W5pts.wt. of a strongly acidic cation exchange resin (based on 1pt.wt. of the starting compound) in acetonitrile and/or 1,4-dioxane. The cation exchange resin in preferably a resin having sulfonic acid group as the exchange group and having excellent solvent resistance, heat-resistance and acid reistance.
