Kinetic Study on Esterification of Oleic Acid with Ultrasound Assisted

As the limitation of nonrenewable energy resourcesand for covering energy demand in future, it is important to search and apply the renewable energy resources which is effective, efficient and sustainable. The literatures of kinetic reaction of biodiesel from oleic acid arerare and most literatures used conventional method. The objective of this research isto examine kinetic reaction of oleic acid esterification which is assisted by ultrasonic wave. Variables that used in this research are catalyst concentration and reaction temperature. Oleic acid and methanol are reacted inside three neck flask and assisted by ultrasonic wave. Gas Chromatography is used to identify contain of FAMEin biodiesel. The highestconversion for the temperature variable is 86.67% at 700C, and the highest conversion for the catalyst variable is 87% at 1.4% wt. Model of kinetic reaction is reversible second order reaction with R2 0.986 for temperature variable and 0.975 for catalyst variable.
