摘要：
Dissociation constant of dihydropyrimidine derivatives has been determined in dimethyl forma-mide-water (60: 40 v/v) system at different temperatures. The data are discussed in terms of the electron nature of the substituents. Further, some thermodynamics parameters such as enthalpy of solution, Gibbs energy change and entropy of solution have also been evaluated for these systems.
