摘要:
为了寻找溶剂的性质对冠醚配位化合物稳定性影响的规律性,用极谱法测定了冠醚15C5在甲醇(MeOH)和乙腈(MeCN)、乙醇(EtOH)和乙腈(MeCN)的混合溶剂中与Pb2+,Co2+,Ni2+,Cu2+等金属阳离子形成的配合物稳定常数logK,并进一步研究了溶剂的性质对配合物稳定性影响的规律性,得出了配合物的稳定常数logK与混合溶剂中乙腈的摩尔分数x的关系
Abstract:
In order to find the regularity of the effect of solvent properties on the stability of crown ether coordination compounds, the stability constant logK of the complex formed by crown ether 15C5 with metal cations such as Pb2+, Co2+, Ni2+, Cu2+ and other metal cations in the mixed solvent of methanol (MeOH) and acetonitrile (MeCN), ethanol (EtOH) and acetonitrile (MeCN) was further determined, and the regularity of the influence of solvent properties on the stability of complexes was further studied. The relationship between the stability constant logK of the complex and the molar fraction x of acetonitrile in the mixed solvent was obtained
