The invention provides a (meth)acrylate represented by the general formula (I)
wherein X is a single bond or an alkylidene group having the general formula (II)
wherein R
3
and R
4
are independently hydrogen atoms or alkyl groups having 1 to 4 carbon atoms, R
1
is a hydrogen atom or a methyl group, R
2
is an alkyl group having 1 to 4 carbon atoms, m is 0 or 1, and when m is 0, n is 3, and when m is 1, n is 0.
The (meth)acrylate is obtained by reacting a cycloaliphatic ketone, an organomagnesium halide and a (meth)acrylic acid ester in the presence of an amine under the industrially feasible reaction conditions and operation according to the invention.
本发明提供了一种由一般式(I)表示的(甲基)丙烯酸酯,其中X是单键或具有一般式(II)的烷基亚甲基基团,其中R3和R4分别是氢原子或具有1至4个碳原子的烷基基团,R1是氢原子或甲基基团,R2是具有1至4个碳原子的烷基基团,m为0或1,当m为0时,n为3,当m为1时,n为0。该(甲基)丙烯酸酯是通过在本发明的工业可行反应条件和操作下,在胺的存在下,将环状脂肪酮、有机镁卤化物和(甲基)丙烯酸酯反应而得到的。
