Preparation of biodiesel from Clean Coffee oil catalysed by PCMCs of CAL B (Grey Bars) and Palatase Black Bars). PCMC was made as described in materials and methods section. Reactions were performed taking 0.5 g coffee oil. Ethanol was added in molar ratio 4:1 (ethanol: oil). Conversion rates were measured by analyzing the aliquots withdrawn at the different time intervals using Gas Chromatographic analysis. The experiments were done in duplicates and the error between the two sets was within 3%.
