| titleOfInvention | Improved Method for Simultaneous Preparation of 6-Aminocapronitrile and Hexamethylene Diamine |
| abstract | The present inventionn n n comprising the steps of: a) hydrogenating adiponitrile in the presence of a catalyst comprising a catalytically active component comprising a Group 8 transition element to obtain a mixture comprising 6-aminocapronitrile, hexamethylenediamine, adiponitrile and a high boiling point material ,n n n b) distilling and recovering hexamethylenediamine from the mixture comprising 6-aminocapronitrile, hexamethylenediamine, adiponitrile and a high boiling point material, andn n n c1) 6-aminocapronitrile is recovered by distillation, and then d1) the adiponitrile is recovered by distillation, orn n n c2) simultaneous distillation of 6-aminocapronitrile and adiponitrile and recovery of the respective fractions. < RTI ID = 0.0 > [0002] < / RTI > The method is characterized in that the temperature of the bottom of the column in step d1) or c2) is less than 185 占 폚. |
