Abstract: Acrylamide is stabilized by the incorporation of 0.001 to 0.3% by weight based on acrylamide of divalent manganese ions which may be added during or after the preparation of the acrylamide. Suitable manganese salts are the halides, phosphates, sulphates and carboxylate which may be added to the acrylamide as solutions in water or lower alkanols. Examples (1) describes the preparation of acrylamide from acrylonitrile and sulphuric acid in which manganous sulphate is added together with the nitrile to 85% sulphuric acid.
