Effect of Intermediate Esters Towards Boundary Lubricity of Palm Methyl Ester

Mechanism of methanolysis, using vegetable oil, methanol, and base-catalyze, is generally used to produce methyl ester. This method is also utilized for the kinetic study of the transesterification process based on the formation of fatty acid methyl esters to differentiate among the intermediate est...
