摘要
用量热滴定法于298.15K测定了高氯酸镧与18—冠—6在无水乙腈溶液中的配位作用.(?)助计算机求得了配合物的稳定常数和配位焓,进而算出了配位自由能和配位熵.配位反应为放热反应.
The coordination reaction of lanthanum pcrchloratc with 18-crown-6 in acctonitrilc was determined at 298.15K by calorimetric titration. The enthalpy of coordination reaction and stability constant of coordination compound were calculated by using computer. Furthermore, the values of free energy and entropy of coordination reaction were obtained. The result show that the enthalpy change is exothermic.
