실험 절차

To 40.126 kg of the reaction product of Example 4a, 15.241 kg of demineralized water and 3.00 kg of L-tartaric acid were added to get a clear solution with a meso-tartaric acid content of 66% of the total amount of tartaric acid. To 99.98 g of this mixture, 49.55 g of a 40 wt % FeCl3-solution in water were added. Using 16.6 g of a 50 wt % of sodium hydroxide solution in water, the pH was set to 4.35. Finally, 1163.6 g of demineralized water were added to obtain the desired final iron concentration.
