Abstract: The invention relates to a method for producing N,N'-carbonylbis- epsilon -caprolactam by the single-stage reaction of epsilon -caprolactam with phosgene, optionally in an inert organic solvent, in the presence of an organic nitrogenous base without an acylable nitrogen atom. The invention is characterised in that the organic nitrogenous base has a pKa-value of between 5 and 7. N,N-dimethylaniline is the preferred nitrogenous base.

Abstract: The invention relates to a method for producing N,N'carbonylbis- epsilon -caprolactam by reacting epsilon -caprolactam with phosgene in the presence of a hydrogen chloride-binding agent in an inert organic solvent and isolating the reaction product from the product solution. The isolation comprises the following steps: a) optionally distilling off a part of the organic solvent from the product solution; b) adding water to the product solution; c) removing the organic solvent by azeotropic distillation, optionally while replacing the water distilled off, thereby deploying the product solution of organic solvent; d) allowing the N,N'-carbonylbis- epsilon -caprolactam to crystallize from the solution that is deployed from organic solvent, thereby obtaining an aqueous suspension of N,N'-carbonylbis- epsilon -caprolactam; and e) removing the crystallized product.

Date Jul. 4, 1996Salts of aromatic hydroxy compounds are used as brighteners in acidic electroplating baths. Furthermore, acidic electroplating baths for the electrolytic deposition of metallic layers onto shaped articles comprise, as brighteners, at least one novel salt of an aromatic hydroxy compound. Finally, shaped articles are electroplated by a process using the novel acidic electroplating baths.
