In this study, an acidic phosphonium-based ionic liquid, namely tributyl(3-sulfopropyl)phosphonium trifluoroacetate, was designed and synthesized via a facile and green route. From an accurate perspective, the structure of the prepared ionic liquid was investigated using FT-IR, 1H NMR and 13C NMR spectroscopies, and EDX, elemental mapping and TGA/DTG analysis. In this intensive research, catalytic
