A mechanistic study : In a Brønsted acid/base reaction, gaseous triflic acid (OTfH) transfers its proton to the basic Cl − anion of the ionic liquid [C 8 C 1 Im]Cl forming volatile HCl and the IL [C 8 C 1 Im][TfO]. This anion exchange reaction is monitored in the near‐surface region quantitatively by X‐ray photoelectron spectroscopy as a function of time (see picture; BE=binding energy).
