摘　　要：为实现对有机反应中均相Brønsted酸的有效捕获祸首,本文以三氟甲基磺酰胺为原料合成了含三氟甲基磺酰亚胺官能团(CF_(3)SO_(2)NHSO_(2))的全氟烷基磺酰亚胺内盐,其结构通过FT-IR,1HNMR,19FNMR手段进行表征。探究内盐分别在CH_(3)NO_(2)和CH_(3)CN这两种纯溶剂体系中对小分子均相Brønsted酸(CF_(3)SO_(3)H、CH_(3)SO_(3)H、H_(2)SO_(4)和对甲苯磺酸等)回收效能的研究。结果显示偶极离子对小分子均相Brønsted酸具有很好的循环回收效果。In order to capture the culprit of homogeneous Brønsted acid in organic reactions,perfluoroalkyl sulfonimides containing trifluoromethyl sulfonimide functional group(CF_(3)SO_(2)NHSO_(2))aresynthesized from trifluoromethyl sulfonamide,its structure ischaracterized by FT-IR,1HNMR,19FNMR.This paper studies therecovery of small homogeneous BRønsted acids such as CF_(3)SO_(3)H,CH_(3)SO_(3)H,H_(2)SO_(4)and Para-Toluene sulfonate in the pure solvent systems of CH_(3)NO_(2)and CH_(3)CN.The results show that the dipole ion has a good recycling effect on the small molecule homogeneous Brønsted acid.
