The present invention discloses a method for producing a fluorine-containing alkyl (meth)acrylate represented by the following general formula (2):
Rf—(CH
2
)
k
-[-A-(CH
2
)
l
—]
m
—OCOCR═CH
2
(2)
(wherein R is a hydrogen atom or a methyl group), characterized by reacting
a fluorine-containing alcohol represented by the following general formula (1):
Rf—(CH
2
)
k
-[-A-(CH
2
)
l
—]
m
—OH (1)
(wherein Rf is a perfluoroalkyl group having 1 to 21 carbon atoms; A is S, SO or SO
2
; k is 0, 1 or 2; 1 is k, 2 or 3; m is 0 or 1; however, a case of k=0 and m=0 is excluded),
(meth)acrylic acid, and
a sulfonic acid halide
in the presence of a base containing at least one kind of tertiary amine.
本发明揭示了一种生产由下述通用式(2)表示的含氟烷基(甲基)
丙烯酸酯的方法:Rf—(
CH2)k-[-A-( )l—]m—OCOCR═ (2)(其中R为氢原子或甲基),其特征在于在至少含有一种三级胺的碱存在下,通过将下述通用式(1)表示的含
氟醇:Rf—( )k-[-A-( )l—]m—OH(1)(其中Rf为具有1至21个碳原子的
全氟烷基;A为S、SO或SO2;k为0、1或2;l为k、2或3;m为0或1;但排除k=0且m=0的情况),与(甲)
丙烯酸和
磺酸卤在碱的存在下进行反应。
