Abstract
PURPOSE: The racemization of an optically active aminoacid is effected in the presence of a lower fatty acid and an aromatic aldehyde to give the racemi aminoacid in high yield through one step and this process is applicable to a variety of aminoacids and the racemization rate is high.
CONSTITUTION: An optically active aminoacid such as alanine, arginine, asparaginic acid or proline is racemized in the presence of a saturated fatty acid of 1W3 carbon atoms and an aromatic aldehyde such as benzaldehyde which may be a substituent such as hydroxyl, nitro, amino, methoxy or the like wherein the amount of the aldehyde is about 0.001W0.3mol and the lower fatty acid is more than 10 (V/V)% based on the optically active aminoacid.
