在２８３．１５～３１８．１５Ｋ（间隔５Ｋ）下，用光度法测定了离子缔合物Ｆｅ（Ｐｈｅｎ）３（ＣｌＯ４）２Ｈ２Ｏ（简写为ＦＰＣ，以下同）在水及甲醇—水混合溶剂中的溶解度．经微机曲线拟合给出溶解度Ｓ随温度Ｔ及甲醇质量百分比浓度Ｗｔ％的经验关系ｌｇＳ＝１．９５８＋１．３０５×１０－２Ｗｔ％－（１５０３．４＋３．０８５×１０－２Ｗｔ％）／Ｔ．用溶剂结构理论对ＦＰＣ溶解度的变化规律进行讨论．
At 283.15 ~ 318.15K (interval 5K), the photonometric method was used to determine the ionic complex Fe (Phen) 3 (ClO4) 2H2O (abbreviated as FPC, the same applies below) in water and methanol- Solubility. The curve fitting of the computer gives the empirical relationship of the solubility S with the temperature T and the mass percentage concentration of methanol Wt% lgS = 1.958 + 1.305 × 10-2Wt% - (1503.4 + 3.085 × 10-2Wt%) / T. Solvent structure theory of FPC solubility changes are discussed.
