Abstract

In this research work, the yield percent of the prepared biodiesel from two selected seeds oil: cotton,Gossypiumbarbadense Linn. and sunflower, Helianthus annuuswere observed (82%, 75%) by transesterification method. The biodiesel derived from crude cotton seed oil, sunflower oil and their degummed oil were found to show similar physicochemical properties such as acid value, cloud point, flash point, pour point, solid point, specific gravity, and viscosity, and no moisture was detected. These fuel related properties were observed to be comparable with ASTM standard data, indicating that the biodiesel prepared from cotton and sunflower seed oil have a good fuel quality and it can be used as an alternative in fuel diesel engines.
