Abstract
A method for optical resolution of a DL-amino acid comprising reacting the DL-amino acid with an optically active N-acyl aspartic acid in a solvent or mixture of solvents, and separating the resulting two diasteromeric salts by way of the difference between their solubilities in the solvent or mixture of solvents. The difference in solubility may be enhanced by cooling, concentration, addition of a solubility-decreasing organic solvent, pH adjustment or salting out.
