Abstract

1. Process for the extraction or concentration of aromatic substances from aqueous solutions, characterised in that the aqueous solution is passed through a bed of silica gel modified with hydrocarbon radicals having 1 to 24 C atoms, whereby the aqueous solution is used in an amount of about 50-1000 l/kg of silica gel, and the bed is subsequently eluted with about 50 to about 500 ml of an organic solvent per kg of silica gel.
