Fe(phen)_3(ClO_4)_2H_2O由水至甲醇-水混合溶剂中的标准迁移自由能

The Standard Free Energies of Transfer of Perchlorate Tris(1,10 Phenanthroline)Iron(Ⅱ)from Water to Methanol Water Mixed Solvent

用光度法测定２８３．１５～３１８．１５Ｋ（间隔５Ｋ）８个温度下ＦＰＣ在纯水及甲醇－水混合溶剂中的溶解度．由溶解度数据计算了ＦＰＣ在水、甲醇－水混合溶剂中的活度系数及由水至甲醇－水混合溶剂中的标准迁移自由能及介质效应，并对ＦＰＣ标准迁移自由能的变化规律进行了讨论．

Solubilities of Fe(phen)3(ClO4)2·H2O in water and Methanol Water mixed solvents at 283.15～318.15K have been determined by the spectrophotometry.The standard Gibbs free energy of transfer of Fe(phen)3(ClO4)2·H2O from water to Methanol Water Mixed Solvent,activity coefficient and medium effect from 283.15K to 318.15K have been calculated.
