METHOD FOR REMOVING METAL IONS FROM CRESOL MIXTURES
摘要
A method for removing metal ions from cresol or aromatic mixtures containing cresol. Water is added and the water content of the cresol mixture is initially adjusted by at least 0.5 %. The cresol/water mixture is subsequently conducted via an acid ion exchanger and a metal ion content of less than 20 ppb per metal ion is obtained.
