Document Type and Number:
Japanese Patent JP2009079024
Kind Code:
A
Abstract:
To provide a method for production by which a 2-naphthol derivative using a 2-tetralone derivative as a raw material can more inexpensively be produced by simpler operation.
The method for producing the 2-naphthol derivative represented by general formula (II) (wherein, X1 to X4 are each a hydrogen or a halogen selected from among fluorine, chlorine and bromine, and at least one thereof is the halogen) comprises dehydrogenating the 2-tetralone derivative represented by general formula (I) with sulfuric acid in the presence of an acid anhydride using a water-immiscible organic solvent and then hydrolyzing the resultant product.
