In a process for producing polyamides, a mixture comprising hexamethylenediamine and aminocapronitrile and obtained from the hydrogenation of adiponitrile is reacted with water and a dicarboxylic acid.

Method for the production of polyamides

The preparation of polyamides, their oligomers or mixtures thereof, where appropriate with other reaction products, takes place by reacting amino nitrites (A) and, where appropriate, other polyamide-forming monomers and/or oligomers with water (D) in a reactive distillation, wherein the reaction product (P) is discharged from the bottom of the reactive distillation apparatus, and ammonia (N) which is produced and, where appropriate, other low molecular weight compounds which are produced, and water, are taken off overhead.
