We report the optimization of sunflower oil methyl esters (SOME/biodiesel) production via alkaline catalyzed transesterification of crude sunflower oil and subsequent physical and chemical characterization. The optimum conditions elucidated for the methanolysis of sunflower oil were found to be: methanol/sunflower oil molar ratio, 6:1; reaction temperature, 60 C; and NaOH catalyst concentration, 1.00% (w/w). An optimum SOME yield of 97.1% was achieved. SOME were analyzed by gas-liquid chromatography (GLC). A number of fuel properties of SOME as measured according to accepted methods were found to satisfy nearly all prescribed ASTM D 6751 specifications, where applicable. The results of the present study indicated that SOME could be a potential alternative to other common biodiesels and petrodiesel. (C) 2008 Elsevier Ltd. All rights reserved.
