摘要: 自1967年C.J.Pedersen首次合成冠醚并发现其配位特性以来,稀土冠醚配合物的研究工作发展迅速[1],特别是对固体配合物的合成及其性质的表征做了大量工作,但对其在溶液中热力学性质的研究却不多见,而且所用方法仅为电位法、NMR法、电导法等,用量热滴定法的报道很少[2]

Abstract: The coordination reaction of lanthanum and ytterbium perchlorates with dibenzo-30-crown-10 in acetonitrile was determined at 298. 15 Kby calorimetric titration. The reaction enthalpies were calculated by using computer. The results show that the enthalpy changes are exothermic.

Key words: Calorimetric titration, Enthalpies of coordination reaction, Rare earth, Dibenzo- 30- crown-10
