Microwave assisted two step in situ method for biodiesel production from jatropha Curcas L. Seed

This study explored the development of two steps process in a batch reactor system capable of operating in a microwave oven irradiation for biodiesel production from jatropha seed by using in–situ method. The first step, in-situ esterification, converted the free fatty acid by H!SO! as acid catalyst and the second step, in-situ transesterification converted the triglycerides by KOH 5N in ethanol as base catalyst in the microwave system. This was also the first investigation, which carried out twostep process from jatropha seed with out any washing and purification between esterification step and transesterification step. Furthermore, microwave irradiation assisted extraction of oil from Jatropha curcas seed with different solvent was carried out for two size seed with diameters of A<0.5 mm & 0.5<B
