An electrochemical technique was used to investigate pKa values of some substituted secondary alicyclic amines (SA amines), pyridines (py), anilines (AN) and triethylamine (Et3N) in different ionic liquids. The method involves cyclic voltammetry at a platinised Pt electrode. The experimental data were correlated with pKa values reported before in aqueous solution and Hammett parameters were correlated with pKa values in ionic liquids to determine ρ values in these media.
