Abstract
In the catalytic hydration of acrylonitrile to produce acrylamide by contacting aqueous solution of acrylonitrile with a catalyst, the solubility of acrylonitrile in the aqueous feed solution is increased by presence of acrylamide cosolvent in the feed solution, enabling feed solutions having concentration of acrylonitrile higher than the saturation concentration of acrylonitrile in water without a cosolvent.
