Workup

  1. 1
    OtherThe water was removed in vacuo
  2. 2
    Temperaturewith heating to approximately 90° C. for 4 hours
  3. 3
    OtherThe product was isolated as a white solid

Procedure

L-Tartaric acid (2.00 g, 13.33 mmol) was dissolved in 5 ml of distilled water. Guanidine carbonate (2.40 g, 13.33 mmol) was added at room temperature (carbon dioxide gas was evolved) and the reaction was stirred at room temperature for 24 hours. The water was removed in vacuo with heating to approximately 90° C. for 4 hours. The product was isolated as a white solid.
