| titleOfInvention | Method for preparing hexamethylene diamine and aminocapronitrile |
| abstract | The present invention relates to a process for the co-production of hexamethylene diamine and aminocapronitrile. More particularly, the present invention relates to a process for the simultaneous preparation of hexamethylene diamine and aminocapronitrile via semihydrogenation of adiponitrile, which comprises separating hexamethylene diamine from hydrides by distillation of hexamethylene diamine. Distillation of hexamethylene diamine is carried out from hydrides containing free acids and / or alkali or ammonium salts. Thus, the upper fraction A recovered at the top of the column of the distillation step of hexamethylene diamine essentially contains crude hexamethylene diamine and a small amount of THA. The amount of THA present in the crude hexamethylene diamine represents a small amount of THA contained in the hydride. |
