本文测定了Cu（acac）_2在11种有机溶剂-0.10M高氯酸盐体系中的分配系数。它们的大小进行了比较，与Hacac的烯醇形式，并评估了一个修改后的方程的基础上正规溶液理论。铜（II）螯合物的分配系数已被证明强烈依赖于一些特定的溶质-溶剂相互作用，如直接配位的中心金属和氢键的配体分子。在氯仿的情况下，特别是特定的相互作用已阐明的缔合反应，其平衡常数已被确定。
Partition coefficients of Cu(acac)2were determined in eleven organic solvents-0.10M perchlorate systems. Their magnitude was compared with that of the enol form of Hacac and evaluated by a modified equation based on the regular solution theory. The partition coefficient of the copper (II) chelate has been demonstrated to strongly depend on some specific solute-solvent interactions such as direct coordination to the central metal and hydrogen bonding to the ligand molecules. In the case of chloroform, particularly the specific interaction has been elucidated by an association reaction, for which the equilibrium constant has been determined.
