Research progress in the catalysts for the ammoxidation of propylene

The acrylonitrile is a basic organic chemical material. It has been widely used in chemical industry. At present, producing acrylonitrile mainly uses the process of propylene ammoxidation. Study on the catalyst of propyl-ene ammoxidation is the key to this process. Advances in the catalysts for propylene ammoxidation is reviewed in the paper, including reaction mechanism, catalyst advance and future trend.
