NiTMPyP的溶液平衡性质研究
Researches on Equilibrium of Nickel(Ⅱ) Tetrakis(4Nmethylpyridyl) Porphyrin in Aqueous Solution
【摘要】 基于β吸收带利用比耳定律和光谱实验研究了浓度大于10-4mol·L-1的NiTMPyP〔meso四(4N甲基吡啶基)卟啉合镍(Ⅱ)〕的溶液平衡性质.结果表明,在该溶液中NiTMPyP以四配位NiTMPyP和六配位NiTMPyP(H2O)2的平衡混合物存在,丙酮和咪唑的加入以不同方式对该平衡产生影响.
【Abstract】 The equilibrium properties of NiTMPyP〔nickel(Ⅱ)tetrakis(4Nmethylpyridyl)porphyrin〕above 10-4mol·L-1 in aqueous solutions were studied with experiments of Beer’s law and spectra based on β absorption bands.The selfmade cell with a thickness of 0.1cm were used in experiments.The results showed that NiTMPyP exists in these solutions as an equilibrium mixture of fourcoordinate NiTMPyP and sixcoordinate NiTMPyP(H2O)2.Acetone and imidazole added exerted different influence on the equilibrium.
