Sodium Hydroxide → 2,3-Dihydroxybutanedioic Acid

Participants

Reaction Steps

Into a test tube were charged 3.40 g of D-tartaric acid, 1.46 g of meso-tartaric acid, 7.78 g of sodium hydroxide and 10.6 g of water. Following the process of Reference Example 1, the racemization of D-tartaric acid was conducted and the reaction mixture was analyzed to give 0.08 g of unreacted D-tartaric acid, 2.62 g of DL-tartaric acid and 1.72 g of meso-tartaric acid. The conversion of D-tartaric acid to DL-tartaric acid was 77.1%.
