Method for removing metal ions from cresol mixtures

A method for removing of metal ions from cresol or from mixtures of aromatic compounds containing cresol is disclosed, wherein the water content in the cresol mixture is adjusted to at least about 0.5 per cent by weight by the addition of water and the water-and-cresol mixture is subsequently passed...

Zusammenfassung:	A method for removing of metal ions from cresol or from mixtures of aromatic compounds containing cresol is disclosed, wherein the water content in the cresol mixture is adjusted to at least about 0.5 per cent by weight by the addition of water and the water-and-cresol mixture is subsequently passed over an acid ion exchanger. As a result of this process a metal ion content of less than 20 ppb per metal ion is achieved.
