The present invention relates to an N-(1-hydroxyethyl)carboxamide compound represented by formula (1)
(in the formula, R
A
and R
B
represent independently from each other a hydrogen atom or an alkyl group having 1 to 4 carbon atoms except for a case where R
A
and R
B
represent a hydrogen atom at the same time) and a method for producing the same; a method for producing an N-(1-alkoxyethyl)carboxamide compound; a method for producing an N-vinyl carboxylic acid amide compound; and a method for producing an N-vinyl carboxylic acid amide (co)polymer. An N-(1-alkoxyethyl)carboxamide compound can be obtained by reacting N-(1-hydroxyethyl)carboxamide compound with alcohol in the presence of an acid catalyst, and an N-vinyl carboxylic acid amide compound, which is a monomer of the N-vinyl carboxylic acid amide (co)polymer, can be obtained by thermally decomposing or catalytically decomposing the N-(1-alkoxyethyl)carboxamide compound.
本发明涉及一种由式(1)表示的N-(1-羟乙基)羧酰胺化合物(在该式中,RA和RB独立地表示氢原子或具有1至4个碳原子的烷基,除非RA和RB同时表示氢原子),以及其制备方法;一种制备N-(1-烷氧基乙基)羧酰胺化合物的方法;一种制备N-乙烯基羧酸酰胺化合物的方法;以及一种制备N-乙烯基羧酸酰胺(共)聚合物的方法。在酸催化剂存在下,可以通过将N-(1-羟乙基)羧酰胺化合物与醇反应来获得N-(1-烷氧基乙基)羧酰胺化合物,而将N-(1-烷氧基乙基)羧酰胺化合物热分解或催化分解可以获得N-乙烯基羧酸酰胺化合物,后者是N-乙烯基羧酸酰胺(共)聚合物的单体。
