摘要：
Crystal of rare-earth perchlorate complex compound with proline was synthesized. By using TG, DTA and chemical analytic method, and comparing with relative literatures, its structure was characterized as [Gd-2(Pro) (6)(H2O) (4)] (ClO4) (6), and it has a purification of 99. 0%. A thermochernical cycle was designed at 298. 15K, measurements of solution calorimetry of the reactants [2GdCl(3) . 6H(2)O + Oro + 6NaClO(4) . H2O] and the products {[ Gd-2 (Pro) (6) (H2O) (4)] (ClO4) (6) + 6NaCl} were carried out in an isoperibel reaction calorimeter, respectively. The calorimetric solvent used was 2mol . L-1 HCl. The chemical reaction and standard enthalpy of formation were calculated as: Delta rH(m)(circle minus) - 46. 829kJ . mol(-1), Delta H-f(m)circle minus([Gd-2(Pro)(6)(H2O)(4)] (ClO4)(6), s, 298. 15K) 6532. 745kJ . mol(-1).
