Abstract (en)
[origin: WO2005005359A1] An improved method for the recovery of phenol from aqueous streams comprises adding a relatively non-polar solvent to a phenol containing aqueous stream to improve the separation of the phenol form the aqueous stream. The improvement results in a phenol stream with a reduced level of salt carried over from the aqueous stream.
