| titleOfInvention | Method of separating unreacted terephthalic acid |
| abstract | A METHOD OF SEPARATING UNREACTED TEREPHTHALIC ACID FROM A REACTION MIXTURE CONTAINING BIS-(B-HYDROXYETHYL) TEREPHTHALATE OBTAINED BY THE ETHYLENE OXIDE PROCESS WHICH COMPRISES TREATING THE REACTION MIXTURE TO FORM A SUSPENSION CONTAINING MOLTEN BIS-(B-HYDROXYETHYL) TEREPHALATE HEATED AT 85*C. TO 180*C. AND SOLID UNREACTED TEREPHTHALIC ACID, IN WHICH SUSPENSION (A) THE CONTENT OF UNREACTED ETHYLENE OXIDE IS LESS THAN 2% BY WEIGHT BASED ON THE BIS-(B-HYDROXYETHYL) TEREPHTHALATE, AND (B) THE CONTENT OF AN INERT ORGANIC LIQUID MEDIUM IN THE SUSPENSION IS 1-100% BY WEIGHT BASED ON THE BIS(B-HYDROXYETHYL) TEREPHTHALATE; AND SEPARATING THE UNREACTED TEREPHTHALIC ACID FROM THIS SUSPENSION. THE RECOVERY OF THE UNREACTED TEREPHTHALIC ACID IS ALMOST 100%. |
