Method for preparing 1,3-dihydroxy-4,6-bis( alpha -methyl- alpha (4'-hydroxyphenyl)ethyl)benzene

摘要

A method for preparing 1,3-dihydroxy-4,6-bis[ alpha -methyl- alpha - alpha (4'-hydroxyphenyl)ethyl]benzene represented by the following formula (1): a reaction of resorcin with 4-isopropenylphenol in a mixed solvent which comprises a non-polar solvent and a polar solvent in the presence of an acidic catalyst. The method can easily be handled, ensures a high yield, permits the reduction of impurity content and can provide highly pure 1,3-dihydroxy-4,6-bis[ alpha -methyl- alpha -(4'-hydroxyphenyl)ethyl]benzene. The resulting phenolic compound is useful as, for instance, a branching agent for polycarbonates, polyesters or the like; a raw material for radiant ray-sensitive components for use as resist materials; a raw material for epoxy resins; and a hardening agent for epoxy resins.
