| description | The present invention relates to a method for preparing halogenated benzonitriles by vapour phase ammoxidation at a reaction temperature comprised in the range of 300 to 500 DEG C in a fixed bed reactor using a three-component catalyst. More particularly, the method of the invention relates to a method for preparing 2,6-dichlorobenzonitrile (2,6-DCBN) from 2,6-dichlorotoluene (2,6-DCT) by vapour phase ammoxidation. The invention also relates to a three-component catalyst provided on a carrier and its use in a vapour phase ammoxidation reaction according to the invention. In addition, the invention provides a method for preparing the three-component catalyst.
L'invention concerne un procédé de préparation de benzonitriles halogénés par ammoxydation en phase vapeur à une température de réaction comprise entre 300 et 500 DEG C dans un réacteur à lit fixe au moyen d'un catalyseur à trois composants. L'invention concerne en particulier un procédé de préparation de 2,6-dichlorobenzonitrile (2,6-DCBN) à partir de 2,6-dichlorotoluène (2,6-DCT) par ammoxydation en phase vapeur. L'invention concerne également un catalyseur à trois composants disposé sur une porteuse et son utilisation dans une réaction d'ammoxydation en phase vapeur. L'invention concerne également un procédé de préparation du catalyseur à trois composants. |
