The physicochemical properties such as densities and speeds of sound have been measured for Jatropha Curcas biodiesel (1) + ethan-1-ol or propan-1-ol (2) binary mixtures over entire composition range at T = (288.15 to 308.15) K and atmospheric pressure. The measured data have been utilized to determine excess molar volumes V12E, isentropic compressibilities (κS)12, and deviations in isentropic compressibilities (ΔκS)12. The V 12E and (ΔκS)12 values were fitted to Redlich-Kister polynomial equation to calculate the adjustable parameters together with their standard deviations. The measured data and derived physical properties have been discussed in terms of the dipole-dipole, dipole induced-dipole interactions, and hydrogen bonding between fatty acid methyl esters (biodiesel) and ethan-1-ol or propan-1-ol molecules and their structural factors.
