Abstract
Biofuel is becoming prominent among the alternatives to conventional petro-diesel due to economic, environmental and social factors. In this paper we have presented a study of the quality of biodiesel influenced by the physical and chemical properties. The values of physical and chemical properties of biodiesel were compared with American Standards and Testing Materials (ASTM). The physico-chemical properties of groundnut oil and reused groundnut oil were assessed for their potential in biodiesel production. We determined acid value, saponification number, Iodine value, cloud point, pour point, kinetic viscosity, flash point, fire point, copper strip corrosion, cetane number, heat of combustion, specific gravity and boiling point. The results show that the groundnut oil produced high quality biodiesel as compared to reused groundnut oil.
