| titleOfInvention | PROCESS TO RECOVER CAPROLACTAMA |
| abstract | 1. Process for recovering caprolactam from a mixture comprising caprolactam, water, light and heavy components, subjecting the mixture to a first vacuum distillation resulting in a first bottom product comprising heavy components and caprolactam and in a first superior product comprising caprolactam, water, unsaturated lactams and light components; and subject at least part of the unsaturated lactams to hydrogenation. 2. Process according to claim 1, characterized in that the process comprises separating the first upper product into a first part containing water and light components and a second part containing caprolactam and lactates not saturated; and hydrogenating said second part. 3. Process according to claim 1 or claim 2, characterized in that the process comprises separating the first superior product by subjecting the first superior product to a second vacuum distillation resulting in a second superior product which it comprises water and light components and in a second background product comprising caprolactam and unsaturated lactams; and hydrogenate said second bottom product. |
