ACRYLONITRILE BY 0000001136 00000 n 0000004432 00000 n Acrylonitrile is produced by Sohio Process based on the wapor-phase catalytic air oxidation of propylene and ammonia, known as ammoxidation. In terms of its molecular structure, it consists of a vinyl group linked to a nitrile.It is an important monomer for the manufacture of useful plastics such as polyacrylonitrile. Propylene and ammonia are reacted in the presence of air at almost stoichiometric quantities at 30 psia and a temperature of 662°F - 1112°F. ����3�2n^޿. Acknowledging the significance of the technology, the American Chemical Society has designated INEOS’ “Sohio Acrylonitrile Process” a National Historic Chemical Landmark.
