Production of Acrylonitrile. 0000044316 00000 n 4 Sohio Process It is the most famous method used by industries in order to produce Acrylonitrile by Propylene. 1. The Sohio process uses a catalyst that selectively accelerates the rate of formation of acrylonitrile without significantly affecting the reaction rates of competing combustion reactions. The process (Figure 1) consists of three major sections: (1) polymerization, (2) purification and (3) finishing. 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. Acknowledging the significance of the technology, the American Chemical Society has designated INEOS’ “Sohio Acrylonitrile Process” a National Historic Chemical Landmark. startxref 0000121908 00000 n Fluidized Bed Reactor Quencher 0000001986 00000 n 210 0 obj <>stream i .
