A simple method for extraction of Ricinus communis L. oil and its application for biodiesel production by ethylic route

Abstract Biodiesel is a clean fuel, and an alternative to the environmental complications ascribed fossil fuels. However, forms of its production are still object research in literature because some issues related process improvement economical viability remain challenge. Consequently, this aims produce biodiesel by ethylic route from Ricinus communis L. oil extracted with simple solid liquid extraction method without use soxhled extractor inspired rural communities practices. In sense, was n- hexane as solvent, obtaining through ethyl transesterification via alkaline catalysis. The characterization terms of—acid value (AV), combustibility corrosivity copper. results indicated that yield 14% relation mass seeds used, AV 0.96 mg NaOH/g, showing case can be used obtain biodiesel. obtained 37% 1.98 being considered above acceptable for diesel engines, should neutralized at least 0.8 NaOH/g. Based on work, esterification easy method.
