| titleOfInvention | PROCESS TO PRODUCE EPSILON-CAPROLACTAMA. |
| abstract | A process for producing ε-caprolactam comprising the steps of: (i) pouring raw ε-caprolactam and a first solvent together into a container, in which the crude ε-caprolactam is molten or dissolved in a second solvent comprising a second solvent aliphatic hydrocarbon and, optionally, a second organic solvent having a greater polarity than that of the second aliphatic hydrocarbon and wherein the first solvent comprises a first aliphatic hydrocarbon and, optionally, a first organic solvent having a greater polarity than that of the first aliphatic hydrocarbon, in which the first aliphatic hydrocarbon may be the same or different than the second aliphatic hydrocarbon and in which the first solvent has a temperature lower than the temperature of the crude ε-caprolactam, and mix the ε-caprolactam and the first solvent to obtain a first suspension containing crystallized ε-caprolactam, in which the temperature crystallizes tion is 30 ° C less than the melting point of ε-caprolactam, and (ii) subjecting the suspension to a solid-liquid separation to obtain ε-caprolactam and a first liquid phase. |
