Abstract

A new solid catalyst, Na/SiO2, which have come in demand recently due to environmental concerns is prepared using the sol gel method by transesterification of jatropha oil with methanol to produce a biodiesel fatty acid methyl ester. Na/SiO2 with a loading of 50:50 molar ratio Na/Si, calcined at 600 °C exhibited the best catalytic activity for the reaction. The conversion of vegetable oil is found to be 99%. The optimum reaction conditions are achieved at the reflux temperature of methanol (65 °C), with a 1:15 molar ratio of methanol to oil and a catalyst amount of 6 wt%. The catalyst showed high activity under mild conditions and at a relatively short reaction time of 45 min.
