An efficient method for the synthesis of secondary alkylamides of phosphorylacetic acids (APA) was proposed. The method involves amidation of ethyl phosphorylacetates with primary aliphatic amines. The scope of reaction was determined. Reactions with ethylenediamine and 1,4-diaminobutane yield the corresponding bisamides; in the case of 1,3-diaminopropane, N-(3-aminopropyl)diphenylphosphorylacetamide
提出了一种合成磷酸乙酸(APA)仲烷基酰胺的有效方法。该方法包括用伯脂肪胺对磷酸乙基乙酸乙酯进行酰胺化。确定了反应范围。与乙二胺和 1,4-二氨基丁烷反应生成相应的双酰胺;在 1,3-二氨基丙烷的情况下,取决于反应条件,获得 N-(3-氨基丙基)二苯基磷酰乙酰胺或 N,N'-丙烯双(二苯基磷酰乙酰胺)。研究了用物理吸附的 APA 从硝酸溶液中提取镅 (III) 配合物和吸附剂对铀 (VI) 的吸附。镅(III)的分配系数与APA的结构没有相关性;在铀(VI)的吸附中,提取程度取决于络合物结构。
