Glutaric Acid → Adipic Acid

Participants

Reaction Steps

The mother liquor with the urea-succinic acid adduct removed was treated with a column of the same strongly acidic ion exchange resin to remove urea. After 120 g. of water was further distilled off, the treated liquid was cooled to and allowed to stand at 15° C. to deposit crude adipic acid. 11.9 g. of crude adipic acid was obtained by filtration. The obtained crude adipic acid contained 2.1% by weight of glutaric acid and 1.3% by weight of succinic acid and may be recycled to a purification step in the production of adipic acid to obtain pure adipic acid.
