Abstract
PURPOSE: To prepare a rosin glycidyl ester, economically, under atmospheric pressure, at a relatively low temperature, by reacting a rosin, an epihalohydrin and an alkali in the presence of an organic basic compound.
CONSTITUTION: The objective rosin glycidyl ester is prepared in high yield, by reacting (A) a rosin such as tall oil rosin, (B) an epihalohydrin such as epichlorohydrin, and (C) an alkali (pref. ≥40wt% aqueous solution of an alkali metal hydroxide), in the presence of (pref. 0.1W3wt% of) an organic basic substance such as triethylamine, pref. under atmospheric pressure, at 70W120°C. The amount of the alkali is pref. 1W1.2 times equivalent of the carboxyl group of the rosin.
