Tetraalkylammonium and tetraalkylphosphonium ions induce oil droplet coalescence in dilute oil/water emulsions stabilized by sodium dodecanoate. This was shown by dynamic light-scattering, monitoring oil droplet sizes, and kinetic measurements of oil droplet aggregation. A large ion size, a symmetrical ion geometry and a strongly interacting counterion were found to be important criteria for organic electrolytes to be efficient demulsifiers.
