| titleOfInvention | PROCESS FOR THE PREPARATION OF ε-CAPROLACTAM |
| abstract | The present invention relates to a process for preparing ε-caprolactam starting from 6-aminocapronitrile, by hydrolysis / oligomerization using superheated steam, followed by de-oligomerization / ringing,n n n The hydrolysis / oligomerization is carried out with superheated steam, converting 6-aminocapronitrile into a gas phase comprising a molten phase and ammonia, the ammonia is continuously separated off and the de-oligomerization / ringing is a superheated steam. Furnace by further treating the molten phase.n n n The present invention also relates to a process for producing ε-caprolactam starting from 6-aminocapronitrile by hydrolysis / oligomerization followed by de-oligomerization / ringing,n n n The production process is carried out in a horizontal scraped-surface reactor, wherein the hydrolysis / oligomerization is carried out with superheated steam, converting 6-aminocapronitrile into a gas phase comprising a molten phase and ammonia, the ammonia continuously Separation and removal, and the de-oligomerization / ringing is carried out by additional treatment of the molten phase with superheated steam. |
