Abstract
The methanolysis of triolein was investigated as functions of an amount of (KOH) and molar ratio (triolein/methanol) by using ultrasonic irradiation to make methyl esters. From the results obtained, we have found the optimum condition to make methyl esters. In addition, the effect of sonication on the methanolysis of triolein was discussed in comparison to that of the sterring.
