Biodiesel, alkyl ester of vegetable oil is an environment friendly renewable non toxic biodegradable diesel fuel produced by the acid or base catalyzed methanolysis of vegetable oil. The optimized reaction conditions are molar ratio of oil to MeOH 1:6, reaction temperature 65 oC and reaction time 35 minute higher catalyst percentage significantly increased reaction rate and production capacity. The maximum catalyst concentration 1.0 wt.% of oil gives the best conversion 96±0.05%. The biodiesel were characterized for their physical and fuel properties including density, viscosity, iodine volume, acid volume, cloud point, pure point, gross heat of combustion and volatility (ASTM). The purity and conversion of the biodiesel was analyzed by HPLC.
