General User Guide for Partitioning of Tetraalkylammonium and Tetraalkylphosphonium Salts: Impacts of Cation, Anion, and Solvent

Using a gravimetric approach, the
partitioning of 57 tetraalkylammonium
and 10 tetraalkylphosphonium salts in 12 different organic solvent/water
mixtures was determined. The data show that the partitioning is dramatically
affected by the identity of the cation, anion, and solvent, and this
comprehensive compilation can serve as a general user guide to aid
as a starting point for reagent selection, especially in cases where
efficient removal of the tetraalkylammonium or phosphonium salt is
required.
