TY - JOUR AB - Transesterification or alcoholysis is the most commonly applied method for biodiesel production. A catalyst is needed to improve the transesterification reaction and yield. The present study used soybean oil as the raw oil to mix with methanol and four strong alkali catalysts (NaOH, KOH, CH3ONa & CH3OK) to undergo a transesterification reaction. Transesterification was carried out using 100% :excess alcohol, i.e., molar ratio of alcohol to soybean oil was 6:1, and, catalyst concentration of 1% at 60 degrees C. Alkali metal alkoxides were found to be more effective transesterification catalysts compared to hydroxides. Sodium methdxide was the most efficient catalyst, although KOH and NaOH could also be used because they are cheaper and are used widely in large scale processing: AD - Dicle Univ, Engn Fac, Min Engn Dept, TR-21280 Diyarbakir, Turkey AN - WOS:000403524100019 AU - Saydut, A.
