Abstract: The present work is focusing on the synthesization and physico-chemical properties of Jatropha curcas biodiesel with diesel and alcohols. The densities of binary diesel (2) + 1-alkanols (C3 or C4) (3) and ternary Jatropha curcas biodiesel (1) + diesel (2) + 1-alkanols (C3 or C4) (3) blends have been reported over full range of composition at temperatures within range 288.15 to 313.15 K. Also densities of Jatropha curcas biodiesel (1) + diesel or 1-alkanols (C3 or C4) (2) blends have been measured at 313.15 K. Excess molar volumes, VE, V123E of binary and ternary blends were calculated from the measured data and the derived properties were correlated to composition using Redlich–Kister equation. A reasonable agreement was found between the measured and estimated values. Further, densities and excess molar volumes data were reasoned to discuss molecular interactions taking into consideration effect of composition and temperature.
