Abstract: Biodiesel comprises of monoalkyl esters of long chain fatty acids. It is produced using edible oil, non-edible oil and animal fats by acid or base catalyzed transesterification with ethanol or methanol. In this research work, the oil was extracted using n-hexane. Response surface Methodology (RSM) with central composite design (CCD) was applied to optimize the biodiesel production from seed oil. An optimum biodiesel yield of 98.32 % was obtained by transesterifying Jatropha seed oil with 0.30 g of catalyst and ethanol to oil molar ratio of 12:1 at 65 oC for 2 hrs. The experimental yield is in good agreement with the predicted yield, with relatively small percentage error (0.58 %). This shows that the proposed statistical model is suitable for prediction of optimized biodiesel yield and for optimization of transesterification process
