| titleOfInvention | PROCESS FOR THE EXTRACTION OF CEPHALEXIN. |
| abstract | Process for the recovery of cefalexin from a mixture containing cephalexin and 7-aminodesacetoxy-cephalosporic acid (7-ADCA), wherein a mixture of cephalexin and 7-ADCA with a pH greater than 7 which, with any solid cephalexin present, at a pH is between 7 and 8.5 homogeneous, is subjected to a pH change until a pH of less than 7.8 is reached, and the solid present is recovered. The process can be particularly suitably applied to the reaction mixture obtained after the enzymatic acylation reaction of 7-ADCA with a phenyl glycine derivative as an acylating agent. In this way, pure cephalexin can be easily recovered. |
