    Abstract: The present invention relates to a process for the dehydrocyanation of aliphatic dinitriles in the vapour phase. More precisely, it consists of a process for the dehydrocyanation of branched, saturated dinitriles, characterised in that vapours of one or more of the said branched, saturated dinitriles are brought into contact with a partially or completely acidified cation exchanger. The branched, saturated dinitriles which are subjected to the dehydrocyanation according to the present process are more particularly 2-methylglutaronitrile, 2-ethylsuccinonitrile, their mixtures with each other or industrial mixtures containing them.

    Abstract: La présente invention concerne un procédé de déshydrocyanation de dinitriles aliphatiques en phase vapeur. Elle consiste plus précisément en un procédé de déshydrocyanation de dinitriles aliphatiques saturés ramifiés, caractérisé en ce que des vapeurs d'un ou plusieurs desdits dinitriles aliphatiques saturés ramifiés sont mises en contact avec un catalyseur comprenant un échangeur de cation partiellement ou complètement acidifié, à une température allant de 300.degree.C à 600.degree.C. Les dinitriles aliphatiques saturés ramifiés qui sont soumis à la déshydrocyanation selon le présent procédé sont plus particulièrement le 2-méthyl-glutaronitrile, le 2-éthyl-succinonitrile, leurs mélanges entre eux ou les mélanges industriels les contenant.
