| titleOfInvention | Process for producing epsilon-caprolactam |
| abstract | A high purity epsilon-caprolactam is prepared by pouring a molten crude epsilon-caprolactam and a solvent comprising an aliphatic hydrocarbon and having a lower temperature than that of the crude epsilon-caprolactam, into a vessel and mixing them to obtain a first slurry containing a crystallized epsilon-caprolactam. The slurry is then subjected to a solid-liquid separation to obtain epsilon-caprolactam and a first liquid phase. This process can effectively remove impurities from a crude epsilon-caprolactam, which is obtained by for example, subjecting cyclohexanone oxime to the Beckmann rearrangement. |
