Synthesis of Isopropyl Esters From Jatropha Curcas Oil At Short Time Reaction

摘要

The searching of environmentally friendly materials that have potential to replacement mineral oil is currently being considered a top priority research topic in the fuel and energy sector. This paper presents the influence of ultrasound-assisted transesterification of jatropha oil to isopropyl ester and the optimum condition. The transesterification was performed by using isopropyl alcohol as solvent in the presence of ultrasound operating frequency constant at 35 kHz. The isopropyl ester content of product was 97.8 % under the the reaction temperature of 60 °C, isopropyl alcohol to jatropha oil molar ratio of 8 : 1 within the reaction time of 15 min.
