| titleOfInvention | Purification of cephalosporin compound |
| abstract | PURPOSE: To obtain a purified cephalosporin compound useful as an antimicrobial or feed additive in a continuous process in high yield, by decomposing a crude cephalosporin compound with a salt in the presence of a specific organic solvent, and by oxidizing the freed compound. n CONSTITUTION: A crude cephalosporin compound of the formula (A is pyridyl ring; R is hydroxyl-substituted phenyl group; Het is 1W4C lower alkyl-substituted tetrazole; M is alkali metal, alkaline earth metal or organic amine salt) is decomposed with a slat in an amide solvent to give a crystalline free acid solvate compound. In this reaction, an organic alcohol or/and keton solvent is present in any stage. Methanol may be cited as the alcohol; acetone, as the ketone. n EFFECT: High purity enough to be administrable to a man or animal, and high yield. n COPYRIGHT: (C)1981,JPO&Japio |
