C H. 3. 0000014229 00000 n 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. Other acrylonitrile producers soon became licensed in the SOHIO process and, in a few years, the production of acetylene-based acrylonitrile was replaced by the SOHIO process. The process The process examined here is a typical continuous cold-emulsion process for producing NBR that contains 33 wt.% of acrylonitrile. trailer Production of Acrylonitrile. xref 210 0 obj <>stream 0000004432 00000 n ACRYLONITRILE BY Acrylonitrile is a clear, colourless flammable liquid with sweet, pungent, irritating odour. 0000003555 00000 n Clipping is a handy way to collect important slides you want to go back to later.
