Coproduction of 6-aminocapronitrile and hexamethylenediamine |
| abstract |
A process for the coproduction of 6-aminocapronitrile (CAN) and hexamethylenediamine (HMD) by treatment of adiponitrile (AND) with hydrogen in the presence of a nickel-containing catalyst at temperatures not below room temperature and elevated hydrogen partial pressure in the presence or absence of a solvent, which comprises, after the conversion based on AND and/or the selectivity based on CAN has or have dropped below a defined value (a) interrupting the treatment of AND with hydrogen by stopping the feed of AND and of the solvent, if used, (b) treating the catalyst at from 150 to 400 DEG C with hydrogen using a hydrogen pressure within the range from 0.1 to 30 MPa and a treatment time within the range from 2 to 48 h, and c then continuing the hydrogenation of AND with the treated catalyst of stage (b). |
