A method for producing a β-alkoxypropionamide including reacting a β-alkoxypropionic acid ester represented by the following formula (1) and an amine represented by the following formula (2) in the presence of a polyol and a basic catalyst, thereby to produce a β-alkoxypropionamide represented by the following formula (3),
wherein, as the polyol, a reaction residue that is generated by the reaction and contains a used polyol is used: (wherein in the formulas, R and R' are independently a C1 to C6 linear, branched or cyclic, saturated hydrocarbon group; R1 and R2 are independently a C1 to C6 linear, branched or cyclic, saturated hydrocarbon group; and R3 is H or CH3).
生产β-烷氧基丙酰胺的方法包括在多元醇和碱性催化剂存在下,使以下式(1)所代表的β-烷氧基丙酸酯与以下式(2)所代表的胺发生反应,从而生成以下式(3)所代表的β-烷氧基丙酰胺,
其中作为多元醇,使用由反应生成并含有已使用的多元醇的反应残留物:(在公式中,R和R'分别是C1到C6的直链、支链或环状饱和碳氢基团;R1和R2分别是C1到C6的直链、支链或环状饱和碳氢基团;R3是H或CH3)。
