摘要
采用分光光度法研究了磺化酞菁在不同醇、水混合溶液中的二聚现象.结果表明:三磺化酞菁、四磺化酞菁钴的二聚常数 K_D 与溶液中 O—H浓度 M_(O—H)之间满足关系 lgK_D=a·M_(O—H)^(+b),式中 a,b是与磺化酞菁配合物有关的参数。
The dimerzation of cobalt(Ⅱ)tetrasulfonate-phthalocyanine(CoTsPc)and trisulfophthalocyanine(S_3Pc)was studied in aqueous alcoholic solution by spectrophotometry. The dimerzation constants K_D were calculated.The realtionship between concentration of O-H in solutions(M_(O-H))and K_D of S_3Pc and CoTsPc were discussed.The equilibrium be- tween K_D and M_(O-H) is: 1gK_D=α·M_(O-H)+b
