  • Phenol resin treatment improvement
    Patent number: 9193652
    Abstract: Methods and systems for purifying phenol. The method can include contacting a feed that includes phenol and an aldehyde containing compound with a first ion exchange material to produce a first treated product. The first treated product can have a pH that is less than a pH of the feed. The first treated product can contain less of the aldehyde containing compound than the feed. The first treated product can be contacted with a second ion exchange material to produce a second treated product. The second treated product can have a pH that is greater than the pH of the first treated product. Each of the first ion exchange material and the second ion exchange material can be a solid, a semi-solid, or a combination thereof.
