At the constant mole of LiCl, the catalytic activities of LiCl-[imidazolium]Cl melts increased with increasing molar ratio of [imidazolium]Cl/LiCl up to 2, but thereafter decreased rapidly. The variation of alkyl groups on the imidazolium ring showed a negligible effect on the catalytic activity, but the number of alkyl groups present on the imidazolium cation exerts a pronounced effect. Catalysis and electrospray ionization tandem mass spectral analysis results of LiCl-[imidazolium]Cl melts imply that the activity of the melt is strongly related to the amount of LiCl2- generated from the melt.
