RECOVERY OF PURE CEPHALEXIN FROM ACIDIC REACTION MIXTURES

RECOVERY OF PURE CEPHALEXIN FROM ACIDIC REACTION MIXTURES

Cephalexin is obtained in a high state of purity and in an advantageous crystalline form from impure solutions by contacting such solutions with acetonitrile, adjusting the pH to near the isoelectric point to cause an acetonitrile solvate of cephalexin to crystallize and suspending said solvate in w...
