The invention concerns in particular hydrocyanation of butadiene into adiponitrile.
Adiponitrile is made by reacting 3-pentenenitrile with hydrogen cyanide.
Methylglutaronitrile is removed to provide an adiponitrile-enriched stream, which is used in a catalyst purification step.
The monomer products generally include HMD, 5-cyanovaleramide (CVAM), adiponitrile (ADN), CL, 6-aminocaproamide (ACAM), and 6ACN.
The invention relates to the field of separation by distillation of 6-aminocapronitrile (ACN) and hexamethylenediamine (HMD) from a mixture comprising ACN, HMD, tetrahydroazepine (THA), adiponitrile (ADN) and low boilers (LB).
The invention relates to a method of producing polyamides in an aqueous reaction mixture that contains a nitrile, selected from 6-aminocapronitrile and adipodinitrile.
