摘要:
It discloses a new industrial crystallization method of Cefuroxime Sodium, wherein supercritical fluid extraction technology and traditional crystalline technology are combined to realize the recrystallization of Cefuroxime Sodium. Processes such as extraction, adsorption, crystallization and drying are carried out with a supercritical fluid, a solvent, an extraction cell and a crystallization tank to realize the recrystallization of Cefuroxime Sodium under a specific pressure at a specific temperature.
