- Some properties are reported for hydrophobic ionic liquids (IL) containing 1-methyl-1-propyl pyrrolidinium [MPPyrro]⁺, 1-methyl-1-butyl pyrrolidinium [MBPyrro]⁺, 1-methyl-1-propyl piperidinium [MPPip]⁺, 1-methyl-1-butyl piperidinium [MBPip]⁺, 1-methyl-1-octylpyrrolidinium [MOPyrro]⁺ and 1-methyl-1-octylpiperidinium [MOPip]⁺ cations. These liquids provide new alternatives to pyridinium and imidazolium ILs. High thermal stability of an ionic liquid increases safety in applications like rechargeable lithium-ion batteries and other electrochemical devices. Thermal properties, ionic conductivities, viscosities, and mutual solubilities with water are reported. In addition, toxicities of selected ionic liquids have been measured using a human cancer cell-line. The ILs studied here are sparingly soluble in water but hygroscopic. We show some structure-property relationships that may help to design green solvents for specific applications. While ionic liquids are claimed to be environmentally-benign solvents, as yet few data have been published to support these claims.
