Optimization, Characterization And Properties Of Biodiesel Produced From Waste Sunflower Frying Oil

Résumé: Biodiesel from renewable resources generally produced with the transesterification of vegetal oils or animal fats. In this study, we have improved the reaction conditions of the transesterification of the sunflower oil outcome in from frying. Fatty acid alkyl ester synthesized were characterized by the FT-IR spectroscopy and the CG-SM. For that, a range of experiences have been made in 25 °C and in 50 °C with different types of alcohols and in reaction times going from 30 to 240 minutes. The best result of fatty acid alkyl ester have been obtained at 25°C using methanol as an alcohol after an hour of reaction. Features of the obtained biodiesel under optimal conditions in particular kinematic viscosity, density, the cloud point and the flash point were determined and compared to ASTM D6751 biodiesel standards. The results show that the produced biodiesel lines with the standards and there is no major difference between EEAG and EMAG features.
