Polyhydric phenols and epoxy resins derived therefrom |
| abstract |
(57) [Problem] To provide a polyhydric phenol containing no impurities without performing a complicated step for removing the impurities. Also provided is an epoxy resin derived from the polyhydric phenol. SOLUTION: A phenol compound and the following general formula (1); (In the formula, R 1 represents a phenylene group, an alkyl-substituted phenylene group, a naphthalene group, an alkyl-substituted naphthalene group, a biphenyl group or .R 2 represents an alkyl-substituted biphenyl group Represents the same or different and represents a hydrocarbon group having 1 to 4 carbon atoms. A polyhydric phenol produced by reacting a raw material containing the compound represented by the formula (1) with an ion exchange resin as a catalyst to obtain a reaction product. |
