A mixed p-<,<-octyIphenoxy-polyoxyethy!ene-ethanol, with 9.7 ethylene oxide units per phenol (OPE9.7), was separated into its component compounds by chromatography. Silicic acid columns were used with mixed chloroform-acetone eluents. The shape of the elution curve suggests that the resolution was sufficient for the isolation of quite pure species. Agreement with the expected distribution of species from the ethylene oxide plus phenol condensation reaction is satisfactory.
