[Problem] The purpose of the present invention is to obtain a multifunctional (meth)acrylate with good yield by an ester exchange reaction of a polyhydric alcohol such as pentaerythritol or dipentaerythritol with a monofunctional (meth)acrylate.
[Solution] A multifunctional (meth)acrylate manufacturing method characterized in that when manufacturing a multifunctional (meth)acrylate by an ester exchange reaction of a polyhydric alcohol with a monofunctional (meth)acrylate, catalyst (A) and catalyst (B) are used together. Catalyst (A): One or more kinds of compounds selected from a group consisting of cyclic tertiary amines with an azabicyclo structure or salts or complexes thereof, amidines or salts or complexes thereof, and compounds with a pyridine ring or salts or complexes thereof. Catalyst (B): One or more kinds of compounds selected from a group consisting of zinc-containing compounds.
[问题] 本发明的目的是通过多元醇(如戊三醇或二戊三醇)与单官能基(甲基)丙烯酸酯的酯交换反应,获得产率高的多功能(甲基)丙烯酸酯。[解决方案] 一种多功能(甲基)丙烯酸酯制备方法,其特征在于,在通过多元醇与单官能基(甲基)丙烯酸酯的酯交换反应制备多功能(甲基)丙烯酸酯时,同时使用催化剂(A)和催化剂(B)。催化剂(A):选自具有氮杂双环结构的环三胺或其盐或络合物、酰胺或其盐或络合物以及吡啶环或其盐或络合物组成的群中的一种或多种化合物。催化剂(B):选自含锌化合物组成的群中的一种或多种化合物。
