New catalyst for preparing 2,6-dichlorobenzyl nitrile by ammonia oxidation process

The said catalyst is a four component one, VaTibPcCrdOx, with V and Ti as main catalyst and P and Cr as cocatalyst. It has the advantages of high activity, selectivity, product yield and product purity, long service life and simple production process, and it can result in molar yield of 85.8%, selectivity of 88.3%, and product purity higher than 99.0%.
