Anticorrosive performance of newly synthesized dipyridine based ionic liquids by experimental and theoretical approaches.

ABSTRACT: Two newly synthetic nontoxic dipyridine-based ionic liquids (P_ILs) with the same chain lengths and different polar groups were investigated: bispyridine-1-ium tetrafluoroborate (BPHP, TFPHP) with terminal polar groups Br and CF₃, respectively, on Carbon steel (CS) in 8M H₃PO₄ as corrosion inhibitors. Their chemical structure was verified by performing ¹HNMR and ¹³CNMR. Their corrosion inhibition was investigated by electrochemical tests, especially as mass transfer with several characterizations: Scanning electron microscope/Energy dispersive X-ray spectroscopy (SEM-EDX), UV-visible, Atomic force microscope, Atomic absorbance spectroscopy, X-ray Photoelectron Spectroscopy and Gloss value.
