Biodiesel was obtained by transesterification of Jatropha curcus oil with anhydrous methanol, ethanol, and various mixtures of methanol/ethanol system. The present research work ultrasonic assisted transesterification of J. curcus oil was carried out in the presence of various mixtures of methanol/ethanol system and potassium hydroxide (KOH) as a catalyst, keeping the molar ratio of oil to alcohol 1:6. The methodology allows for the reaction to be run under atmospheric conditions. The ethanomethanolysis and ultrasonic mixing promote the rate of transesterification reaction due to the better solubility of oil with ethanol in reaction mixture and obtained methyl esters as well as ethyl esters.
► The ultrasound-assisted method for biodiesel production is faster and easier. ► The aim of using mixture of methanol and ethanol is to accelerate the rate of reaction. ► The present system includes operational simplicity, mild reaction conditions and high conversion. ► Since ultrasonication could reduce the transesterification reaction time.
