Abstract
PURPOSE: To prepare a less colored and highly pure aminophenoltriglycidyl compound useful as a raw material for preparation of an epoxy resin having a high heat distorsion temperature, in high yield, by reacting aminophenol with epichlorohydrin in a specific alcohol solvent.
CONSTITUTION: An aminophenoltriglycidyl compound is prepared by reacting aminophenol with exess amount of epichlorohydrin in a 4W6C alcohol solvent at 10W50°C for 10W30 hr in the presence of a lithium salt catalyst, e.g. LiOH, etc., and dehydrochlorinating the product with an alkali. The 4W6C alcohol solvent is, e.g. n-butanol, sec-butanol, n-pentanol, and n-hexanol and the preferable amount is 0.5W5.0 parts by weight on the basis of 1 part by weight of the aminophenol.
EFFECT: It can be easily separated and purified and the addition reaction proceeeds in comparatively short time. Little by-production of polymer during the reaction.
