Abstract

The polyhydric phenol is reacted with from 2.5 to 10 moles an epihalohydrin per hydroxy equivalent in the presence of a condensation catalyst, water, and an oxygen-containing volatile organic solvent, and dehydrohalogenated with aqueous alkali metal hydroxide, with separation of aqueous phase and organic phase in one or more stages and recovery of the polyglycidyl ether from the last organic phase, at least part of at least one separated aqueous phase being recycled to an earlier stage of the process.
