Ammoxidation of 2,6-dichlorotoluene to 2,6-dichlorobenzonitrile was carried out at atmospheric pressure using VPO catalysts. Different catalyst supports were used and their influence on the catalytic performance has been evaluated. Nature of support has shown clear influence on the activity and selectivity behaviour of the catalysts. Higher activity (X-DCT > 90%) and selectivity (S-DCBN > 75%) along with good long-term stability could be successfully achieved over TiO2 (anatase) supported VPO catalyst. |
