Abstract

Abstract N-3-Aminoalkyl propionamides with an ether substituent on the beta carbon atom are prepared by the reaction of analogous N-3oxohydrocarbon-substituted amides with an amine in the presence of a reducing agent, preferably hydrogen and a hydrogenation catalyst. The resulting compounds can be converted to acrylamides by pyrolysis in the presence of a strong base. The latter compounds may so be prepared by the reaction of an Alpha , Beta -unsaturated amine with an acrylonitrile in the presence of sulfuric acid. They are useful for improving dyeability of fiberforming polymers and may be polymerized to form compositions which improve paper strength and (in their quaternized form) are excellent flocculants.
