Summary:
The aim of the present work was to the preparation of biodiesel from sunflower oil and ethanol by the transesterification reaction in the presence of the KOH. The conversion was 88% at using a 1:3 molar ratio of oil to alcohol at 75°C. Important fuel physical properties of B10 blend with (or without) oxygenated additivities by the ASTM standards had been investigated. Based on the obtained results is noted that the fuel blend B10 with (or without) additivities has greater potentials for diesel engines than, B100 and fossil diesel.
