Abstract
PURPOSE: To obtain the purified acrylamide which does not change with time, by (I) oxidizing partly an aqueous solution of the drude acrylamide, while keeping the oxygen concentration in the said solution equal to or higher than a specific value, and then (II) eliminating copper and other impurities from the oxidized solution by the treatment with ion-exchange resins.
