Self reliance in energy is vital for overall economic development of our country. The need to search for alternative sources of energy which are renewable, safe and non- polluting assumes top priority in view of the uncertain supplies and frequent price hikes of fossil fuels in the international market. Biodiesel (fatty acid methyl ester) which is derived from triglycerides by transesterification, has attracted considerable attention during the past decade as a renewable, biodegradable and nontoxic fuel. Several processes of biodiesel fuel production have been developed, among which transesterification using alkali as a catalyst gives high level of conversion of triglycerides to their corresponding methyl ester in a short duration. This process has therefore been widely utilized for biodiesel fuel production in number of countries. As the acid value of Jatropha curcas oil is high, so that we have to reduce it by the process of esterification followed by transesterification. The methyl ester produced by this way gives the good result.The present study deals with transesterification of jatropha curcas oil which gives >83% of methyl ester and >17% of glycerol using molar ratio 6:1(methyl alcohol to oil) and 0.5wt % of sodium hydroxide at 65c for 90 minutes and allowed to settle overnight. As per ASTM 6751(American Standards For Testing and Material) the properties like density, viscosity, flash point, cloud point and pour point have been carried out at Indian Biodiesel Corporation, Baramati for accessing the fuel quality of Jatropha oil methyl ester.
