Abstract:
The volatilisation of ferrocene (Fc), dissolved in the ionic liquid N ‐butyl‐ N ‐methylpyrrolidinium bis(trifluoromethylsulfonyl)imide, [C 4 mpyrr][NTf 2 ], to the gas phase has been indirectly monitored by cyclic voltammetry and chronoamperometry. Simulation of the observed trends in concentration with time using a simple model allowed quantification of the process. Volatilisation of dissolved Fc under flowing wet and dry dinitrogen gas (N 2 ) was found to be kinetically limited with a rate constant in the region of 2×10 −7 cm s −1 . The activation energy of diffusion for Fc was found to be 28.2±0.7 kJ mol −1 , while the activation energy of volatilisation of Fc from [C 4 mpyrr][NTf 2 ] to dry N 2 was found to be 85±2 kJ mol −1 .
