| titleOfInvention | PROCEDE FOR RECOVERY OF A β-LACTAM ANTIBIOTIC |
| abstract | The present invention relates to a method for recovering β-lactam antibiotics from a mixture containing β-lactam antibiotics and D-phenyl glycine in a solution.n n n At the concentration at which FG remains in solution, the pH of the mixture containing β-lactam antibiotics and D-phenyl glycine (FG) is brought to pH 3-8, the solid β-lactam antibiotics obtained are recovered, and solid β Forming a slurry with lactam antibiotic and solid FG, bringing the pH of the slurry to a pH at which the β-lactam antibiotic is dissolved, separating the FG as a solid, and using at least a portion of the β-lactam antibiotic present in the mother liquor Send the residual liquid to the concentration stage,n n n Corresponding β-lactam nuclei, in particular 6-aminophenicylanic acid, 7-aminodesacetoxycephalosporanic acid and 7-amino-3-chloro-cef-3-m-4-carboxylic acid, are D-phenyl glycine derivatives It is preferred to use an initial mixture which actually contains β-lactam antibiotics and FG derived from the enzyme acylation reaction which is acylated with. |
