Abstract

A process for preparing a substantially purified aqueous indole solution, which comprises dissolving crude indole containing organic impurities in a water-immiscible organic solvent wherein said impurities have a larger partition coefficient than said indole has between said solvent and water, and bringing the solution into contact with water or an aqueous reaction medium to form two liquid phases and transfer the indole to the aqueous phase by partition.
