Procedure
The mother liquor with the urea-succinic acid adduct removed was treated with AMBERLYST 15 as used in Example 3 to remove urea. 200 g. of ethanol was distilled off from the filtrate with urea removed. On cooling to and allowing to stand at 15° C., crude adipic acid crystallized out of the filtrate and 9.3 g. of crude adipic acid was obtained by filtration. The obtained crude adipic acid contained 2.8% by weight of glutaric acid and 1.1% by weight of succinic acid and may be recycled to a purification step in the production of adipic acid to obtain pure adipic acid.
