A polyfluoroalkyl ester of unsaturated carboxylic acid is produced in high yield in a more simple reactor and with much more reduction in the waste than the conventional process based on esterification reaction by subjecting a polyfluoroalkanol represented by the following general formula:
Rf-R—OH
, where Rf is a polyfluoroalkyl group having 1-6 carbon atoms and R is an alkylene group having 1-6 carbon atoms, and an unsaturated carboxylic acid to dehydration reaction in a fluorine-containing solvent in the presence of an acid catalyst and a polymerization inhibitor.
通过在含
氟溶剂中,在酸催化剂和聚合
抑制剂的存在下,通过将以下一般公式表示的多氟烷基醇(Rf-R—OH,其中Rf是具有1-6个碳原子的多氟烷基基团,R是具有1-6个碳原子的烷基基团)与不饱和
羧酸进行脱
水反应,可以在更简单的反应器中高产率地生产不饱和
羧酸的多氟烷基酯,且废物减少比传统的酯化反应过程更多。
