Title: METHOD OF CONSISTENTLY PRODUCING DIALLYLBISPHENOLS
Abstract:
The purpose of the present invention is to provide a method of consistently producing high-quality diallylbisphenols with high yields from bisphenols. This method involves steps (1) through (3) below, and enables the consistent production of diallylbisphenols from bisphenols. (1) A step for reacting allyl halides and bisphenols or alkali metal salts thereof in a cellosolve solvent in the presence or absence of basic alkali metal salts, (2) a step for separating inorganic salt by-products from a reaction solution obtained in step (1), and (3) a step for heating and subjecting to a rearrangement reaction the reaction solution obtained in step (2).
