In the present work, the potential of novel cultivar of safflower seed crop with highest 52% oil contents is evaluated for the first time as a feedstock for biodiesel synthesis. The specific aim of this study was to optimize the transesterification process for maximum biodiesel yield using different parameters and to evaluate its fuel compatibility with mineral diesel. Fatty acid methyl esters (FAMEs) of safflower oil were produced by standard transesterification process using potassium hydroxide (KOH) as catalyst. Optimum biodiesel yield of 98% achieved at 65 degrees C, 5:1 methanol: oil molar ratio, 0.32 g catalyst concentration, and reaction time of 80 min. The kinematic viscosity@ 40 degrees C (cSt), flash point, sulfur contents (wt%), pour point and cloud point of pure safflower oil biodiesel (SOB) were found to be 5.32 mm(2)/s, 80 degrees C, 0.00041%, -9 degrees C and -11 degrees C, respectively. These together with other fuel parameters were in accordance with ASTM standards. The results obtained indicate that SOB appears to be the potential feedstock for biodiesel production and can be used as an alternate source of fuel in diesel engines.
