METHOD FOR WORKING UP RESIDUE IN PRODUCING 8-16C CARBOXYLIC ACID |
| 摘要 |
PROBLEM TO BE SOLVED: To provide a method for working up residues in producing a 8-16C carboxylic acid. SOLUTION: The method comprises isolating degradation acids of low oxidizing agent content and low metal content formed in producing a carboxylic acid, in particular the 8-16C dicarboxylic acid and recirculating a metal catalyst to the production process for the (di)carboxylic acid.
