安替比林及其4位取代衍生物是较强的配位剂,可与不同的稀土盐作用生成组成各不相同的配合物,为了进一步探讨安替比林的衍生物对稀土离子的配位作用,我们研究了以4-一氯乙酰基安替比林(4-ClCH_2COAP)为配体与硝酸镧或氧化镧的三元水盐体系。 1 试剂 LaY_3·nH_2O(Y,n;=NO_3~-,6;Cl~-,7):一定量的La_2O_3逐渐加入稍过量的1∶1的HY酸溶液中,搅拌反应,水浴上蒸发浓缩,冷却,加晶种结晶,抽滤,晶体用蒸馏水重结晶后于干燥器中干燥,经分析符合组成。
Antipyrine and its 4-substituted derivatives are strong complexing agents, which can form complexes of different compositions with different rare earth salts. In order to further explore the effect of antipyrine derivatives on rare earth ions We investigated the ternary water-salt system with 4-chloroacetylantipyrine (4-ClCH 2 COAP) as ligand and lanthanum nitrate or lanthanum oxide. 1 reagent LaY_3 · nH_2O (Y, n; = NO_3 ~ -, 6; Cl ~ -, 7): a certain amount of La_2O_3 gradually added to a slight excess of 1: 1 HY acid solution, the reaction was stirred on a water bath and concentrated by evaporation, Cooling, crystallization seed crystals, suction filtration, the crystals were recrystallized with distilled water and dried in a desiccator, the analysis in line with the composition.
