The objective of this study was to prepare, characterize and test the catalytic properties of iron and gallium salts of Aquivion^® PFSA (hereinafter Aquivion-H). The samples were characterized by the determination of metal loading in fresh and used materials, ATR-FTIR, and thermogravimetric analysis (TG-DSC). The salts were screened in Friedel–Crafts acylation of some heterocyclic compounds and compared with some homogeneous and heterogeneous Lewis acids as well as with pure Aquivion-H. These new salts revealed efficient catalytic activity and recyclability.

Aquivion的新颖铁和镓盐^® PFSA：合成，表征和一些催化应用

本研究的目的是制备，鉴定和测试的Aquivion的铁和镓盐的催化性能^® PFSA（以下Aquivion-H）。通过确定新鲜和二手材料中的金属含量，ATR-FTIR和热重分析（TG-DSC）来表征样品。在某些杂环化合物的Friedel-Crafts酰化反应中筛选了这些盐，并与一些均质和异质路易斯酸以及纯Aquivion-H进行了比较。这些新的盐显示出有效的催化活性和可回收性。
