Green synthesis of biodiesel from jatropha oil and comparative study of biodiesel synthesized from traditional and green synthesis method

Abstract

Green chemistry concerned with developing process and product to reduce or eliminate hazardous substance. One of the goals of green chemistry is to prevent the pollution at its source and to get maximum yield of product. We developed green ways of obtaining biodiesel from jatropa oil using enzymatic catalyst for the trans-esterification reaction. We have synthesized biodiesel from jatropha oil, by using methyl alcohol with base catalyst and ethyl acetate with enzyme catalyst via transesterification reaction and characterized above prepared biodiesel by both processes. We have also compared the characteristic of prepared biodiesel from green method and traditional method i.e. which is prepared by methyl alcohol in presence of base and ethyl acetate with enzyme catalyst via transesterification reaction. It is found that the biodiesel which is prepared by enzyme catalyst give maximum yield, good quality and eco-friendly as compared to the methyl alcohol with base catalyst method. Biodiesel is of great interest because it enables motor vehicle transport using a renewable resource, while reducing the amount of CO2 from fossil fuels being released into the environment. Enzyme catalyzed trans-esterification reactions have the advantage that strong acids/bases are not required, resulting in safer and non-corrosive processes.
