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
