PROCEDURE FOR PREPARATION OF AMINONITRILE AND DIAMINE. |
| abstract |
Process for preparing an aminonitrile and a diamine by catalytic hydrogenation of an aliphatic dinitrile having 3 to 12 carbon atoms, possibly in the presence of a solvent, characterized in that the final reaction mixture, of which the catalyst has been previously separated, it is acidified by adding a sufficient amount of a mineral or organic acid, before extracting by distillation the reaction products and the non-transformed dinitrile. |
