| titleOfInvention | A kind of extraction recovery method of penicillin sulfoxide |
| abstract | The invention discloses a kind of extraction recovery method of penicillin sulfoxide, it comprises the following steps：A, penicillin sulfoxide solution carries out impurity separation by resin adsorption；B, resin desorption obtains penicillin sulfoxide stripping liquid；C, penicillin sulfoxide stripping liquid applies mechanically dissolving penicillin sulfoxide or concentrated penicillin sulfoxide crystal solution；D, crystal solution is crystallized with acid for adjusting pH, then filtered, washing, dry penicillin sulfoxide.This method can be used for extraction recovery penicillin sulfoxide in low concentration penicillin sulfoxide solution, so as to improve the yield of penicillin sulfoxide, reduces production cost, reduces environmental pollution.E, the penicillin sulfoxide produced with this technology is prepared its subsequent product 7ADCA, Cefradine, cefalexin, the product quality such as cefadroxil are improved.F, the pharmaceutical composition that Cefradine, cefalexin, cefadroxil and pharmaceutically acceptable carrier are formed is for respiratory tract infection, urinary tract infections and the skin soft-tissue infections such as the acute tonsillitis caused by treating sensitive bacteria, angina, tympanitis, nasosinusitis, bronchitis, pneumonia etc.. |
