Abstract
PURPOSE: To obtain the titled compound of low viscosity with the easy separation without formation of by-products and coloring, by the addition reaction of epichlorohydrin with an aminophenol in a solvent having a high boiling point, e.g. ethylene glycol, and the dehydrochlorination of the resultant reaction product.
CONSTITUTION: Epichlorohydrin is subjected to the addition reaction with an aminophenol or an alkyl substitution product thereof in the presence of a catalyst, e.g. lithium hydroxide, in a water-soluble having a boiling point ≥120°C, preferably ≥150°C, and the resultant product is then dehydrochloriminated with an alkali metallic hydroxide, e.g. sodium hydroxide, to give a polyepoxy compound. The resultant compound is a light yellow or yellow liquid substance, having a viscosity of 12W25 poises at 25°C, and capable of giving a cured article having improved heat resistance by a curing agent.
