buy High quality of D(-)-Glutamic acid 6893-26-1

D-glutamic acid was prepared from L-glutamic acid by esterification, racemization, chemical resolution and hydrolysis. L-2, 3-dibenzoyltartaric acid (L-DBTA) is reacted with DL-glutamic acid-& gamma;-ethyl ester in aqueous solution at 65-70 °c to form a diastereomeric salt, cooled to 0-5 °c, D-glutamic acid · L-DBTA salt was precipitated, filtered and hydrolyzed to obtain D-glutamic acid. The yield was 85% and the optical purity was over 99%.
