Abstract

NaOH-catalyzed transesterification of Jatropha curcas oil for ethyl ester production in 11-L batch reactor was optimized in this study. Interaction of temperature, NaOH-to-oil molar ratio, ethanol-to-oil molar ratio, reaction time and their effects on ethyl ester purity were also determined. It was found that only NaOH- to-oil molar ratio, interaction of temperature to NaOH-to-oil molar ratio, interaction of ethanol-to-oil and NaOH-to-oil molar ratio and the interaction of temperature to ethanol-to-oil molar ratio have significant effects on ethyl ester purity. At 38°C, (1:7.77:0.34) oil-to-ethanol-to-NaOH molar ratio and 3.77hrs reaction time, optimum production of ethyl ester having 98.02% purity can be achieved. Optimization was done using Response Surface Methodology. Costing was done to serve as criterion for choosing the optimum condition and ethyl ester purity was analyzed using Thin Layer Chromatography.
