실험 절차

14 g. of urea was further added to the mother liquor with the urea-glutaric acid adduct removed and dissolved at 50° C., then subjected to cooling to and allowing to stand at 15° C. for 5 hours to deposit a urea-succinic acid adduct. 44 g. of urea-succinic acid adduct (including 20 g. of succinic acid) was obtained by filtration. The thus obtained urea-succinic acid adduct was dissolved in 500 g. of methanol at 30° C. and treated with AMBERLYST 15 (trade name of a strongly acidic ion exchange resin manufactured and sold by ROHM AND HAAS, U.S.A.) to remove urea. Then, 300 g. of methanol was distilled off and the solution was cooled to and allowed to stand at 20° C. to deposit succinic acid. By filtration 17.9 g. of succinic acid having a purity of 98.3% was obtained.
