Glutaric Acid → Adipic Acid

Participants

Reaction Steps

The mother liquor with the urea-succinic acid adduct removed was treated with AMBERLYST 15 to remove urea and cooled to and allowed to stand at 15° C. after 200 g. of methanol had been distilled off, to deposit crude adipic acid. By subjecting the solution to filtration, 11.0 g. of crude adipic acid was obtained. The obtained crude adipic acid contained 1.8% by weight of glutaric acid and 1.6% by weight of succinic acid. This crude adipic acid may be recycled to a purification step in the production of adipic acid to obtain pure adipic acid.
