苯氧乙酸的一些衍生物有特殊的生理作用,用作植物生长控制剂等.带有苯氧乙酸基团的这类配位体,其醚氧原子的配位能力引起人们的注意,与稀土的配合物研究也有一些报道.在第Ⅰ报中合成了带苯氧乙酸基团的氨羧酸型配位体邻羟基苄胺-N,N,O-三乙酸(HBATA),并测得了0.1 MKCl 水溶液中30℃时的 HBATA 酸离解常数及其与一些二价金属离子的配合物稳定常数.本文用 pH 滴定法测求了0.1 MKNO_3水溶液中30℃时HBATA与钇(Ⅲ)、镱(Ⅲ)的配合物稳定常数,同时还测了此条件的 HBATA 酸离解常数,制得 HBATA 与钇(Ⅲ)、镱(Ⅲ)的1∶1固体配合物,分析了组成并研究了它们的溶解度、电导、磁矩、红外光谱和综合热谱.
Some derivatives of phenoxyacetic acid have special physiological functions and are used as plant growth controlling agents, etc. Such ligands with phenoxyacetic acid groups attract people’s attention due to the coordinating ability of ether oxygen atoms, There are also some reports on the study of complex I. In the first report synthesized with the phenoxyacetic acid group of carboxylic acid ligand ortho hydroxybenzylamine -N, N, O-triacetic acid (HBATA), and measured 0.1 The HBATA acid dissociation constants at 30 ℃ in MKCl aqueous solution and their stability constants with some divalent metal ions have been determined by pH titration method.The effects of HBATA and yttrium (Ⅲ), ytterbium (Ⅲ) ), And the HBATA acid dissociation constants were also measured to obtain a 1: 1 solid complex of HBATA with yttrium (Ⅲ) and ytterbium (Ⅲ). The composition and the solubility, Conductivity, magnetic moment, infrared spectroscopy and integrated thermometry.
