| titleOfInvention | A kind of method of enzymatic clarification cefalexin mother liquor recycled |
| abstract | The invention discloses a kind of methods of enzymatic clarification cefalexin mother liquor recycled, and include the following steps：1）Under certain temperature, with acid solution adjusting cefalexin mother liquor to pH value to 2.0 ~ 3.0；2）Above-mentioned mother liquor is adsorbed, is washed, desorption operation, obtains the solution after desorption；3）Solution after obtained desorption is crystallized with ammonium hydroxide, is filtered, washed, is dried cefalexin finished product；4）By step 3）In filtrate decompression distillation；5）By the disposing mother liquor after the above-mentioned ethyl alcohol distilled and distillation, the dissolving of preparation and preceding 7 ADCA of synthesis for next strippant.Preparation method this method of the present invention is easy to operate, of low cost, energy conservation and environmental protection；Meanwhile using cefalexin made from the method for the present invention compared to the yield higher for not recycling cefalexin made from mother liquor. |
