DCBN is an important fine chemical and can be prepared by the gas‐phase ammoxidation of DCT.However，only a few pa‐pers were dedicated to this route and low yields were often obtained due to the low reactivity of the methyl group from the steric hindrance of the two neighboring bulky and elec‐tron‐withdrawing chlorine atoms.Most of the catalysts for the ammoxidation of DCT were focused on VPO[15，16，18–21].In this work，nanocrystalline Cr VO4 produced by solvothermal reaction was found to have interesting catalytic performance for the ammoxidation of DCT to DCBN.The findings along with some typical literature results are listed in Table 2.
