Measurement and Correlation of Solubility of Some Synthetic Dihydropyrimidines in Dimethylsulfoxide at (298.15 To 318.15) K

Shipra Baluja, Rahul Bhalodia, Ravi Gajera


The solubility (x) of some derivatives of dihydropyrimidines in dimethylsulfoxide was measured by a gravimetry method from (298.15 to 318.15) K under atmospheric pressure and some thermodynamic parameters such as Gibbs free energy, enthalpy and entropy of solutions have been evaluated. The solubility is found to increase with temperature.
