Abstract

See full text

The present application relates to an extraction reactor with which granular material, in particular granular polyamide, can undergo extraction, soluble components being dissolved out of the granular material with an extraction liquid during the extraction. In the case of polyamide materials, these are for example oligomeric or monomeric components which have remained in the granular material during the polycondensation reaction for the production of the polyamide materials.
