Abstract

Die Erfindung betrifft ein Verfahren zur kontinuierlichen Extraktion von Polyamidteilchen mit im Kreislauf geführter Extraktionslösung in einer senkrechten, in zwei Zonen unterteilten Extraktionskolonne, wobei man das Polyamid in der ersten Zone mit einer wässrigen ε-Caprolactamlösung mit 40 bis 95 Gew.-% ε-Caprolactam als Extraktionsmittel bei 100 bis 140 °C behandelt und dann in der zweiten Zone mit Wasser nachbehandelt. Anschliessend kann das Caprolactam in an sich bekannter Weise extrahiert werden. Das Verfahren erlaubt eine wirtschaftliche Herstellung von Polyamid mit geringem Dimergehalt.
