Disclosed is a method for the production of adipodinitrile by hydrocyanation of 1,3-butadiene on a catalyst, wherein in a first step 1,3-Butadiene is hydrocyanated to form 3-Pentene nitrile on at least one nickel(0) catalyst and, in a second step, 3-Pentene nitrile is hydrocyanated to form adipodinitrile on at least one nickel(0)-catalyst by adding at least one Lewis acid. At least one of the at least one nickel(0) catalysts used in the respective steps of the inventive method is converted in the other step.

L'invention concerne un procédé pour produire de l'adipodinitrile par hydrocyanuration de 1,3-butadiène sur un catalyseur. Ce procédé consiste, au cours d'une première étape, à hydrocyanurer du 1,3-butadiène pour obtenir du 3-pentènenitrile sur au moins un catalyseur nickel(0) et, au cours d'une deuxième étape, à hydrocyanurer le 3-pentènenitrile résultant pour obtenir de l'adipodinitrile sur au moins un catalyseur nickel(0), avec addition d'au moins un acide de Lewis. Cette invention est caractérisée en ce qu'au moins un des catalyseurs nickel(0) utilisés lors des étapes de procédé respectives est réutilisé au cours de l'autre étape de procédé.
