Title:
METHOD FOR WORKING UP RESIDUE IN PRODUCING 8-16C CARBOXYLIC ACID
Document Type and Number:
Japanese Patent JP2003306465
Kind Code:
A
Abstract:
To provide a method for working up residues in producing a 8-16C carboxylic acid.
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.
