Abstract

An 11-L batch reactor was used for the transesterification of Jatropha curcas L oil using methanol as alcohol and sodium hydroxide as catalyst. The response surface methodology (RSM) was used to optimize the conditions for the methyl ester purity of at least 96.5%. The model generated by the Design Expert 7.1.6 to illustrate the interactions between Methanol-to-oil ratio, NaOH-to-oil ratio, temperature and reaction time was a Quadratic model.The operating cost of the optimum conditions predicted from the model was calculated to determine the most economical condition while maintaining the minimum methyl ester purity at 96.5%. The best reaction condition having a low operating cost was described by a methanol to oil molar ratio of 7.43, NaOH to oil molar ratio of 0.14, reaction temperature of 54.625 C and reaction time of 20 minutes with a purity of 99.33%.
