| Title of Invention | PROCESS FOR THE MANUFACTURE AND SEPARATION OF DINITRILE COMPOUNDS |
|---|---|
| Abstract | The present invention relates to a process for the manufacture and separation of dinitrile compounds.It relates more particularly to a process for the manufacture and separation of dinitrile compounds from a medium originating from the hydrocyanation of unsaturated mononitriles.The invention consists in feeding the medium comprising the dinitriles to a distillation column and then recovering the purified dinitriles as intermediate fraction, the heavy products being removed as column tail fraction and the light products, including the unsaturated mononitriles, being recovered as top fraction. |
