Abstract
Methods and systems for purifying a crude aniline. The method can include contacting a crude aniline that can include aniline, water, and cyclohexanone with a cation exchange resin to produce a cyclohexanone-lean product that contains less cyclohexanone than the crude aniline. The cation exchange resin can be a solid, a semi-solid, or a combination thereof.
