Abstract
Dry acrylamide is produced by reacting acrylonitrile with from 0.3 to 1 mole of water in the presence of a metallic nitrile conversion catalyst. The reaction is conducted under conditions of pressure and temperature and other reaction conditions to convert at least 30% by weight of the nitrile to acrylamide. This reaction produces a solution of acrylamide dissolved in nitrile which then is either treated by means of cooling or pressure reduction to precipitate acrylamide crystals from the reaction mixture, which crystals are then recovered.
