FURAN-2,5-DICARBOXYLIC ACID PURGE PROCESS |
| 摘要 |
Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid. |

1. A process to produce a catalyst rich stream, said process comprising:
(a) contacting a mother liquor stream in a solvent recovery zone to form an impurity rich waste stream; wherein said mother liquor stream is produced in a 5-HMF oxidation process; and (b) routing a portion of said impurity rich waste stream to a catalyst recovery zone to form a catalyst rich stream. |
