  • How is Ricinus communis oil produced?
  • Ricinus communis L. oil was produced applying a simple method. Ricinus communis L. seeds were collected in Lichinga, Mozambique. The following was used used in this process; n-hexane (Supra Solvs), 95% diethyl ether (Rochelle Chemical); 99.9% ethanol and 37% HCl-RPE, Brande: CARLO ERBA.
  • Can Ricinus communis oil be used for biodiesel production?
  • The extraction of Ricinus communis L. oil, is mainly performed applying sophisticated techniques, such as, Soxhlet, CO 2 supercritical fluid and among others [ 17, 18 ]. However, as far as we known, no works in literature was found that applied a simple and traditional approach to obtain Ricinus communis L. oils for biodiesel production.
  • What is Ricinus communis used for?
  • The Ricinus communis L., belongs to the family Euphorbiaceae, it can nowadays be found in most of tropical countries [ 8 ]. The seeds of Ricinus communis, are generally used for biodiesel productions, because they allow an easy production [ 7, 8, 9, 10 ]. Soxhalet and solvent extraction are commonly used for Ricinus communis L. oils production.
  • How was Ricinus communis extracted?
  • 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.
  • What is the yield of biodiesel derived from Ricinus communis?
  • The yields in terms of oils is better than other sources such as (soyben: 15–20% (p/p), sunflower: 25–35% (p/p), colza: 38–46% (p/p) e palm: 30–60% (p/p) [ 12 ]. Furthermore, the biodiesel produced from Ricinus communis L. oil presents properties that are in agreement with the quality standard of biodiesel [ 13 ].
  • How is biodiesel obtained from ethyl esterification of Ricinus communis oil?
  • Based on this work, biodiesel was obtained via ethyl esterification of Ricinus communis L. oil extracted from a simple and easy method. Biodiesel is fuel from biomass; this is renewable, clean, biodegradable, non-toxic, sulfur free among other advantages.
