The extraction of itaconic acid from fermentation liquor by ion exchange method has been realized. Best results were obtained by first passing the fermentation liquor (diluted 3 times by water) through a column of cation exchange resin, Amberlite IR‐120, then through a column of strong basic anion exchange resin, Amberlite ira‐401, and eluting the itaconic acid out by 3 N NaOH. The elution was complete when the volume of elutriant reached one‐half of the volume of the influent, in so far as the part already adsorbed on the resin is concerned. This brought the concentration of itaconic acid to two fold in a single run, and resulted in the decolorization at the same time. It was found that Amberlite IR‐45 (OH) can also be used to extract the acid 100% complete, but the column used should be twice as long, and the volume of the 3 N NaOH elutriant should be increased three times. On account of the complicated nature of the molasses, the adsorption of the acid on the resins was only 57–66%complete. The improvement of the extraction by using methods such as selective coprecipitation prior to the extraction is under way.
