titleOfInvention | Process to separate epsilon-caprolactam from 6-aminocaproamide and 6-aminocaproamide oligomers |
abstract | Process to separate .epsilon.-caprolactam from 6-aminocaproamide and 6-aminocaproamide oligomers, wherein .epsilon.-caprolactam, 6-aminocaproamide and 6-aminocaproamide oligomers are present in a first aqueous starting mixture, which mixture is contacted with an alcohol extraction solvent, resulting in a first aqueous raffinate phase which is poor in .epsilon.-caprolactam and an alcohol phase which is rich in .epsilon.-caprolactam and which alcohol phase contains 6-aminocaproamide and/or 6-aminocaproamide oligomers, wherein the latter alcohol phase is subsequently contacted with water (backwash water) resulting in an alcohol extract phase poor in 6-aminocaproamide and/or 6-aminocaproamide oligomers and a second aqueous raffinate phase rich in 6-aminocaproamide and/or 6-aminocaproamide oligomers. |
