| titleOfInvention | A kind of method for purifying and recovering cefotaxime acid from cefotaxime sodium |
| abstract | A method for purifying and recovering cefotaxime acid from cefotaxime sodium belongs to the technical field of compound synthesis. The cefotaxime sodium is used as a raw material, the cefotaxime sodium is dissolved in water in the presence of a protective agent, and then decolorized by a decolorizing agent Treatment, adding crystallization solvent to the decolorized solution, adjusting pH<6 to carry out crystallization, suction filtration and drying to obtain cefotaxime acid. The method is simple, can realize the purification and recovery of cefotaxime acid from unqualified cefotaxime sodium, has high recovery rate, realizes the reuse of unqualified products, and avoids waste. |
