PROCESS FOR SIMULTANEOUSLY PREPARING 6-AMINOCAPRONITRILE AND HEXAMETHYLENE DIAMINE |
摘要 |
The invention concerns a process for simultaneously preparing 6aminocapronitrile and hexamethylene diamine proceeding from adipodinitrile. The process is characterized in that: (1) adipodinitrile is partially hydrogenated in the presence of a catalyst in order to obtain a mixture containing 6-aminocapronitrile, hexamethylene diamine and adipodinitrile; (2) 6-aminocapronitrile and hexamethylene diamine are separated from the mixture; (3) between 0.01 and 10 wt %, relative to adipodinitrile, of an acid or an acidic ion exchanger is added to the part substantially containing adipodinitrile, and the adipodinitrile is separated from the mixture; and (4) the adipodinitrile is returned to step (1).
