Ionic liquid buffers: a new class of chemicals with potential for controlling pH in non-aqueous media

Abstract

Ionic liquids with buffering characteristics, synthesized by the reaction of [RMIM] OH base moieties with phthalic and tartaric acid, respectively, are potential reagents for controlling pH in non-aqueous media; remarkable [ Base]/[ Acid] molar ratio dependence of the catalytic activities has been observed in the hydrogenation of olefins with [RuCl2(PPh3)(3)] complex in DMF and [BMIM][BF4].
