Process for Recovering Caprolactam |
| abstract |
"PROCESS TO RECOVER CAPROLACTAMA". The invention relates to a process for recovering caprolactam from a mixture comprising caprolactam, water and light and heavy components by subjecting the mixture to a first vacuum distillation, resulting in a first bottom product comprising heavy components and caprolactam. and in a first top product comprising caprolactam, water, unsaturated lactams and light components; and subjecting at least part of the unsaturated lactams to hydrogenation. |
