실험 절차

Monopotassium D-glucarate (30.0 g, 120.87 mmol) was spooned into a 2 L Erlenmeyer flask containing deionized water (300.0 mL) and mixed well. Dowex 50WX8 ion-exchange resin (H+ form, 72.0 mL, 2.1 meq/mL) was washed with deionized water until the aqueous wash was colorless. The resin was added to the Erlenmeyer flask and the mixture stirred for 4 h. The resin was removed by filtration, washed with deionized water and stored for regeneration. The filtrate was concentrated to a syrup using a freeze dryer (20.8 g, 108.28 mmol, 89.6%, calculated as 100% D-glucaric acid) and, without further purification, redissolved in deionized water to give a D-glucaric acid (1) aqueous solution (ca. 1 M, 108.3 mL).
