Abstract

Densities and viscosities of 6-(4-chlorophenyl)-1, 2, 3, 4-tetrahydro-2,4-dioxopyrimidine-5-carbonitrile have been measured at different concentration in 60% dimethyl sulphoxide (DMSO) in the temperature range 298 to 313 K. The John-Dole equation was used to determine the viscosity. Gibb’s free energy (∆G), entropy change (∆S) and enthalpy change (∆H) were evaluated from relative viscosity . The negative sign of ∆G and ∆H and positive sign of  ∆S indicates the spontaneity of reaction according to thermodynamics.
