Ammoxidation - Wikipedia
网页In organic chemistry, ammoxidation is a process for the production of nitriles (R−C≡N) using ammonia (NH3) and oxygen (O2). It is sometimes called the SOHIO process, acknowledging that ammoxidation was developed at Standard Oil of Ohio. [1][2] The usual substrates are alkenes.
Revised Mechanism of Propylene Ammoxidation | SpringerLink
网页2021年1月26日 · Some twenty years earlier, in the late 1950s–early 1960s, the revolutionary one-step ammoxidation process, the conversion of propylene, ammonia, and oxygen (air) to acrylonitrile using a Bi-Mo-oxide-based catalyst was invented at SOHIO, an endeavor in which I was intimately involved.

Ammoxidation - an overview | ScienceDirect Topics
网页Ammoxidation is the process of conversion of a methyl group to a nitrile in the presence of a heterogeneous catalyst. It can be performed in the vapor phase with a partial insertion to selectively insert nitrogen from gaseous ammonia into an activated methyl group, which may be bonded to olefin, aromatic, and N-heteroaromatic compounds.
