“…It is suggested that these differences were influenced by the cetane number of each substance, which is a parameter directly associated with fuel combustibility, so with the transesterification there was an increase in the cetane number of Ricinus communis L oil (converted into BR) [10]. Generally, the cetane number of biodiesel is much higher than that of mineral diesel, which justifies the fact that biodiesel has a more controlled ignition and burns better in the engine than mineral diesel oil itself [15]. On the other hand, the BR, DP and B20 flame were similar, with the advantage that the BR flame was controlled.…”

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

“…Methanol is generally added in higher proportions than the stoichiometric ratio (3: 1), to change the equilibrium position of the reaction towards the product side. However, this fact strongly increases the final cost of the process, due to the fact that expenses with methanol are higher [15].…”
