A method for separation of eighteen phthalate esters involving the isomers by thin-layer chromatography using polyamide was examined. When developed with methanol-water systems, all of the compounds tested were clearly separated on the plates, showing typical patterns in reversed phase partition chromatography. The solvent systems most suitable for the separation of the isomers were also found, The technique will be applicable to a clean-up procedure in the analysis by gas-liquid chromatography.
