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.
                            具有β碳原子上的醚基取代基的N-3-
氨基烷基丙酰胺可通过类似的N-3-氧代碳氢代取代酰胺与胺在还原剂(最好是
氢气和氢化催化剂)的存在下反应制备而成。所得化合物可在强碱存在下通过热解转化为
丙烯酰胺。后者的化合物也可通过β,γ-不饱和胺与
丙烯腈在
硫酸存在下反应制备而成。它们有助于提高纤维形成聚合物的染色性能,可聚合形成在造纸制造中有用的组合物,并且(在其季
铵化形式下)是优秀的絮凝剂。
