Procedure

40 g. of urea was further added to the mother liquor with the urea-glutaric acid adduct removed and dissolved therein at 60° C. On cooling to and allowing to stand at 15° C. for 5 hours, a urea-succinic acid adduct crystallized out of the solution. By filtration, 50.7 g. of urea-succinic acid adduct (including 20.6 g. of succinic acid) was obtained.
