tri-basic acidとは 意味・読み方・使い方

This polymerizable 2-imidazoline derivative is obtained by reacting a 2-imidazoline compound with a tri-basic acid monoanhydride in essentially equi-molar ratio, and further reacting (meth)acrylic acid glycidyl ester in essentially equi-molar ratio to the above tri-basic acid monoanhydride.例文帳に追加

２−イミダゾリン化合物と三塩基酸の一無水物とを実質的に等モル比で反応させた後、さらに（メタ）アクリル酸のグリシジルエステルを前記三塩基酸の一無水物に対して実質的に等モル比で反応させてなる重合性２−イミダゾリン誘導体。 - 特許庁
