Continuous polyamide extraction process |
| abstract |
A process is disclosed for continuously extracting polyamide particles from a circulating extraction solution in a vertical extraction column subdivided into two zones. The polyamide is treated in the first zone with an aqueous epsilon -caprolactam solution with 15-40 wt. % epsilon -caprolactam as extraction agent at 100 to 140 DEG C, and water is then used in the second zone as extraction agent at a temperature 5-40 DEG C lower. The process allows polyamides with a low monomer and oligomer content to be economically extracted. |
