| titleOfInvention | Process for the production of terephthalic acid |
| abstract | A TEREPHTHALIC ACID SLURRY IN ACETIC ACID IS PRODUCED BY OXIDISING P-XYLENE IN ACETIC ACID, REMOVING WATER BY EVAPORATION OF A STREAM OF WATER AND ACETIC ACID, AND RETURNING ACETIC ACID TO THE OXIDATION STEP. THE TEREPHTHALIC ACID IS SEPARATED FROM THE REACTION MEDIUM IN A FIRST ZONE TO LEAVE A DEPOSIT ON A BAND, THE DEPOSIT IS WASHED WITH A FIRST AQUEOUS MEDIUM IN A SECOND ZONE, REMOVED FROM THE BAND IN A THIRD ZONE, AND ADMIXED WITH A SECOND AQUEOUS MEDIUM. REACTION MEDIUM IS PASSED FROM THE FIRST ZONE TO THE OXIDATION STEP AND TEREPHTHALIC ACID IS RECOVERED, PREFERABLY AFTER FURTHER PURIFICATION. |
