Fast, easy ethanomethanolysis of Jatropha curcus oil for biodiesel production due to the better solubility of oil with ethanol in reaction mixture assisted by ultrasonication.
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.
