The hexamethylenediamine, 6 aminokapuronitoriru and 6 aminokapuronitoriru from the blend which includes tetorahidoroazepin and separation of the hexamethylenediamine

摘要

This invention 6 aminokapuronitoriru (ACN) and the hexamethylenediamine (HMD), ACN, HMD and tetorahidoroazepin (THA), the adiponitrile (ADN) and the field of separation due to the distillation from the blend which boiling point ones (LB) is included low regards. It is ideal in production of the nylon 6,6, method in order to form the distillate flow which includes HMD is disclosed. The leftover flow from distillation of the blend especially is ideal in use with production of the nylon 6 from caprolactam and caprolactam, furthermore it can distill in order to form the distillate which includes ACN and THA. Process condition of method of this invention 2 shianoshikuropenchiridenimin (CPI) is disadvantageous in formation.
