Abstract: The present invention provides an epoxy compound which is 2,2?,7,7?-tetraglycidyloxy-1,1?-binaphthalene. Also, the present invention provides a method for producing [1,1?-binaphthalene]-2,2?,7,7?-tetraol, the method including a step of bringing a crude product produced by dimerization reaction of naphthalene-2,7-diol or a naphthalene-2,7-diol derivative into contact with an aromatic solvent; a step of separating [1,1?-binaphthalene]-2,2?,7,7?-tetraol dissolved in the aromatic solvent from insoluble substances; and a step of removing the solvent from a solution of [1,1?-binaphthalene]-2,2?,7,7?-tetraol. The present invention also provides a method for producing an epoxy compound, the method including reacting [1,1?-binaphthalene]-2,2?,7,7?-tetraol or [1,1?-binaphthalene]-2,2?,7,7?-tetraol monohydrate with epihalohydrin.
