Methods and compositions for improving the extraction of phenols from crude styrene using an aqueous caustic solution are disclosed. It has been discovered that aromatic or alkylammonium tailed multi-polyether headed surfactants and/or quaternary polyamines will improve this extraction, particularly in propylene oxide styrene monomer systems.
