| titleOfInvention | A kind of method of 7-ADCA disposing mother liquors |
| abstract | The invention discloses a kind of methods of 7 ADCA disposing mother liquors, it is characterised in that includes the following steps：1. with the pH value of 7 ADCA mother liquors of lye tune；2. by 7 ADCA mother liquors utilize resin adsorption, then with parsing agent desorb, the feed liquid after being parsed；3. the feed liquid after parsing is carried out hyperfiltration treatment with the clarification that cleans, mixing dialyzate is obtained；4. mixing dialyzate is carried out nanofiltration concentration, concentrate is obtained；5. replacing partial purification water, reuse to 7 ADCA ring expansion acid to dissolve post concentrate.The present invention is by adsorbing the mother liquor after reaction, parsing the operation of attached, ultrafiltration, nanofiltration, with obtained concentrate dissolving penicillin ring enlargement acid.This method is easy to operate, of low cost, energy conservation and environmental protection, and yield improves, meanwhile, the 7 ADCA purity handled by disposing mother liquor are high. |
