| titleOfInvention | The method and apparatus of continuous production epsilon-caprolactams |
| abstract | The present invention provides a kind of method of continuous production ε caprolactams, this method contains in order, a) by i) oleum and/or sulfuric acid and ii) cyclohexanone oxime is input to Beckmann rearrangement area；B) mixture of the caprolactam containing ε of generation is discharged from Beckmann rearrangement area；C) ammonia is added to the mixture of the caprolactam containing ε；D) ammonium sulfate is isolated from the mixture of the caprolactam containing ε；E) ε caprolactams are extracted from the mixture of the caprolactam containing ε in organic solvent；F) add water conservancy and from the ε caprolactams of extraction remove organic solvent in distillation zone with distilling；It is characterized in that the reaction heat that at least part of Beckmann rearrangement area generates exchanging to distillation zone.The present invention also provides the ε caprolactams suitable for implementing the equipment of the above method and being obtained according to the above method. |
