Abstract
PURPOSE: To obtain the titled substance useful as a raw material for epoxy resins with a reduced halogen content advantageously, by dehydrohalogenating the reaction product between an aminophenol and an epihalohydrin with a specific amount of an alkali at a specified temperature.
CONSTITUTION: The reaction product between an aminophenol and an epihalohydrin is dehydrohalogenated with a concentrated aqueous solution of an alkali to give the titled compound. The dehydrohalogenation is carried out at a temperature of 65W100°C by using the akali in an amount of 1.5W2.5 times the stoichiometrically necessary one. The method is industrially advantageous due to the titled compound with a halogen content of 1wt.% or less under various conditions, and applicable to any of the o-, m-, or p- aminophenol without causing side reactions. The reaction proceeds completely, and NaOH or KOH is preferably used in a 45W 55wt.% aqueous solution as the alkali.
