摘 要:<正> Titration calorimetry has been used to study the thermodynamics of reaction in toluene solution of2-thenoyltriflueroacetone(TTA)complexes of rare earths(RE=Y,Nd,Eu,Yb)with N,Ndimethylheptyl-acetamide(N503)at 298.15 K.The heat of the reaction was determined with a TRONACModel 1250 automatic isoperibol calorimeter.The data and figures of titration curve were recorded by the com-puter automatically.An iterative technique of least-square analysis was used to calculate the equilibrium con-stants and the thermodynamic functions including the entropy and free energy changes,minimizing the errorsquare sum by a computer program.
