The extent of the reaction was explored using a convertibility esters (FAEEs) by the transesterification reaction of rubber seed oil (RSO) in parameter, which corresponds to the maximum ester content attainable from the feedstock. The supercritical methanol and ethanol without using any catalyst. Experiment were carried out highest FAME and FAEE contents achieved were % and , respectively. Results in a batch reactor, and reactions were studied at show that transesterification of RSO in methanol o was more efficient than that in ethanol; the temperature had the strongest influence. 260, 280, 300 and 320 C at a pressure of MPa with various mole ratios of ethanol – to Keywords: biodiesel, supercritical, ethanol, methanol, rubber seed oil. 1. INTRODUCTION The transesterification of vegetable oil using an alcohol at supercritical conditions comprises a method used to produce biodiesel and has gained growing interest due to the benefits related to the environment and quality of the fuel generated [1-4]. Alcohol provides the alkyl group that substitutes the fatty fraction of triglyceride and short chain alcohols such as methanol, ethanol, and butanol are the most Trang 128 frequently employed. There are several sources of vegetable oil suitable for production of biodiesel such as palm oil, jatropha, soy bean and some selected species of forest .
