自本世纪三十年代发现氨羧络合剂以来,特别是从1945年发现EDTA(乙二胺四乙酸)的分析应用及Schwarzenbach建立了EDTA络合滴定法后,人们对各种氨羧络合剂进行了广泛的探索。除了熟悉的含脂肪链的化合物外,还合成了含芳环、杂环等类型的化合物。在氨羧络合剂的分子中引入一元、二元或多元酚能增加氨基氮原子的碱性,提高配位能力,且使其具有显色功能和氧化-还原性质。苏联学者在这方面发表了许多工作。本文对含芳环和酚羟基的氨羧络合剂的合成、结构、成络性质及应用做一简单的介绍。
Since the discovery of Ammonia-Carboxylic Complex in the 1930s, especially since the discovery of EDTA (ethylenediaminetetraacetic acid) in 1945 and the establishment of an EDTA complexometric titration method by Schwarzenbach, Agents have been extensively explored. In addition to the familiar fatty chain-containing compounds, compounds of the type containing aromatic rings, heterocycles and the like are also synthesized. The introduction of mono-, bi- or polyhydric phenols into the molecules of the ammonia-carboxyl complexing agent can increase the basicity of the amino nitrogen atom, increase the coordination ability, and make it have the color-developing function and oxidation-reduction property. Soviet scholars published a lot of work in this area. In this paper, the synthesis, structure, network properties and applications of amidocarboxylates containing aromatic rings and phenolic hydroxyl groups are briefly introduced.
