最近在一些文献中,经常可以看到氨羧络合剂这个名词,它在分析化学里得到了广泛的应用。其中特别是氨羧络合剂Ⅲ以简化分析操作和加速元素测定过程中所起的重大作用,引起了化学工作者们的极大注意。因此,笔者认为有必要对氨羧络合剂的类别、制备、性质及应用等方面作扼要阐述,使更进一步的了解它在化学过程中所起的作用,有所帮助。氨羧络合剂自1936年起就已提出,1945年后施瓦尔津巴赫及其同事们着手深入研究,到现在已有二十多年了。它是一个氨基多羧酸,以及它至少有两个残余的乙酸与一个氮原子相结合的衍生物。其中最简单的是最原始的即亚氨基代二乙酸
Recently, in some literatures, the term ammonium carboxyamide complex can often be seen, which has been widely used in analytical chemistry. Among them, especially the ammonia-carboxy-complexing agent III, has greatly attracted the attention of the chemists for simplifying the analysis and speeding up the important role played by the element determination. Therefore, I think it is necessary to make a concise exposition of the types, preparation, properties and applications of AMC, which will help to further understand its role in the chemical process. It has been proposed since 1936 that after Schulz Zimbach and his colleagues began intensive research after 1945, it has been more than twenty years now. It is an aminopolycarboxylic acid and its derivatives with at least two residual acetic acids combined with one nitrogen atom. The simplest of these is the most primitive iminodiacetic acid
