The present invention relates to a method for producing mixtures of monoolefinic C5-mononitriles with non-conjugated C=C- and CN-bonding by catalytic hydrocyanuration of a 1,3-butadiene-containing hydrocarbon mixture, which is characterized in that initially the proportion of those constituents impairing catalytic hydrocyanuration is reduced in the hydrocarbon mixture, and the mixture obtained thereby is subsequently catalytically hydrocyanurated.
La présente invention concerne un procédé pour la préparation de mélanges de mononitriles C¿5? monooléfiniques à liaison C=C et C?N non conjuguée, par hydrocyanuration catalytique d'un mélange d'hydrocarbures contenant du 1,3 butadiène. Ce procédé est caractérisé en ce que l'on réduit dans le mélange d'hydrocarbures d'abord la proportion des constituants altérant l'hydrocyanuration catalytique et en ce que l'on procède ensuite à l'hydrocyanuration catalytique du mélange ainsi obtenu.
