Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An epoxy resin composition consisting essentially of an epoxy compound and a curing agent; wherein the epoxy compound is 2,2′,7,7′-tetraglycidyloxy-1,1′-binaphthalene. 2. A cured product produced by curing the epoxy resin composition according to claim 1 . 3. An epoxy resin composition consisting essentially of an epoxy compound and a curing agent; wherein the epoxy compound is produced by a method comprising reacting [1,1′-binaphthalene]-2,2′,7,7′-tetraol or its monohydrate with epihalohydrin. 4. A cured product produced by curing the epoxy resin composition according to claim 3 .
