| titleOfInvention | PROCESS FOR THE RECOVERY OF A β-LACTAM ANTIBIOTIC |
| abstract | Process for the recovery of a β-lactam antibiotic from a mixture containing the ammonium salt of the β-lactam antibiotic and the ammonium salt of the corresponding β-lactam core by subjecting the mixture to a physical treatment, for instance a treatment of stripping with steam or an inert gas or (steam) distillation at reduced pressure, in which ammonia is released from the ammonium salts that are present and is carried off as such and the precipitate of the β-lactam antibiotic released is recovered. The mixture for instance is the reaction mixture obtained after an enzymatic acylation reaction in which the β-lactam antibiotic is prepared from the corresponding β-lactam core and the corresponding acylation agent. Preferably, the mixture obtained after recovery of the precipitate of the β-lactam antibiotic is returned to the enzymatic acylation reaction. In such a process essentially no β-lactam core and β-lactam antibiotic are lost. Moreover, the enzyme can be re-used many times. |
