PURPOSE:To produce the titled compound useful as an electronic material, etc., in high yield and purity and low hydrolyzable chlorine content, by reacting a brominated alkylphenol with epichlorohydrin, and carrying out dehydrochlorination reaction with an alkali in two steps. CONSTITUTION:A brominated alkylphenol of formula I (R is >=1C alkyl; n is 1-3) is subjected to the addition reaction with epichlorohydrin in the presence of a catalyst such as tetraethyl ammonium bromide, and the obtained brominated alkylphenyl chlorohydrin ether is subjected to the dehydrochlorination reaction with excess epichlorohydrin using an aqueous solution of an alkaline compound while removing the water together with epichlorohydrin by azeotropic distillation under reduced pressure. After removing the excess epichlorohydrin, the resultant brominated oxirane derivative is dissolved in an organic solvent, and the second dehydrochlorination reaction of the residual hydrolyzable chlorine is carried out with an alkaline compound to obtain the objective compound of formula II. |
