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.
