摘要 Titration calorimetry has been used to study the thermodynamics of reaction in toluene solution of 2-thenoyltriflueroacetone(TTA)complexes of rare earths(RE=Y,Nd,Eu,Yb)with N,N dimethylheptyl-acetamide(N503)at 298.15 K.The heat of the reaction was determined with a TRONAC Model 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 error square sum by a computer program.
