PROCESS FOR PRODUCTION OF A CARBOXYLIC ACID/DIOL MIXTURE SUITABLE FOR USE IN POLYESTER PRODUCTION

摘要

THE PRESENT INVENTION RELATES TO A PROCESS BY WHICH A CARBOXYLIC ACID/DIOL MIXTURE IS OBTAINED FROM A CARBOXYLIC ACID/SOLVENT SLURRY WITHOUT ISOLATION OF A SUBSTANTIALLY DRY CARBOXYLIC ACID SOLID. MORE SPECIFICALLY, THE PRESENT INVENTION RELATES TO A PROCESS BY WHICH A TEREPHTHALIC ACID/ETHYLENE GLYCOL MIXTURE IS OBTAINED FROM A TEREPHTHALIC ACID/SOLVENT SLURRY WITHOUT ISOLATION OF A SUBSTANTIALLY DRY TEREPHTHALIC ACID SOLID.
