The invention provides a fluorinated aromatic sulfonic acid catalyst in which sulfonic acid groups and aryl groups substituted by fluorine atoms or fluoroalkyl groups are bound to a matrix selected from the group consisting of polysiloxane and inorganic base material. This catalyst can be produced by introducing sulfonic acid groups and aryl groups substituted by fluorine atoms or fluoroalkyl groups into the above-described matrix. This catalyst is used in various acid-catalyzed reactions such as esterification, acylation, nitration, alkylation, etherification, etc., particularly acid-catalyzed reactions in the presence of water to show a high acid catalysis activity. In addition, since this catalyst is solid, its handling is so easy that recovery and reuse thereof is easy.
本发明提供了一种氟化芳香磺酸催化剂,其中磺酸基团和被氟原子或氟烷基取代的芳基与选自聚硅氧烷和无机基础材料组成的基体结合。将磺酸基团和被氟原子或氟烷基取代的芳基基团引入上述基质中,即可生产出这种催化剂。这种催化剂可用于各种酸催化反应,如酯化、酰化、硝化、烷基化、醚化等,特别是在有水存在的情况下进行的酸催化反应,具有很高的酸催化活性。此外,由于这种催化剂是固体,其处理非常容易,因此很容易回收和再利用。
