Description

ABSTRACT:
N-3-Aminoalkyl propionamides with an ether substituent on the beta carbon atom are prepared by the reaction of analogous N-3-oxohydrocarbon-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 also be prepared by the reaction of a .beta.,.gamma.-unsaturated amine with an acrylonitrile in the presence of sulfuric acid. They are useful for improving dyeability of fiber-forming polymers and may be polymerized to form compositions which are useful in paper manufacture and (in their quaternized form) are excellent flocculants.
