“…Firstly, there is a variety of natural occurring epoxy vegetable oil, mainly Vernonia galamensis [68] and Euphorbia lagascae oil [69], which contain up to 70% of vernolic acid (12S,13R-epoxy-9-cis-octadecenoic acid). The second option consists of the production of oil from genetically modiied seeds which already contains vernolic acid in order to increase its content [70,71].…”

Grape processing produces a substantial amount of residues that are highly polluting and expensive to treat, being grape seed one of the main by-products with high commercial interest. During the extraction process of grape seed oil, most of the nutraceutical compounds remain on the solid cake. This book chapter resumes the potential utilization of grape seed oil for producing biobased materials through environmentally friendly processes that could substitute petroleum-derived products. Special atention is given to transesteriication and epoxidation processes. The transesteriication of grape seed oil in presence of methanol drives to the production of a biodiesel with excellent low-temperature properties. According to EN 14214, grape seed oil-based biodiesel presents a slightly lower cetane number than the speciied limit. In addition, this biodiesel presents a low oxidation stability which can be improved by the incorporation of oxidation stabilizer. Atending to the epoxidation of grape seed oil, short reaction times and high temperatures are advised. Epoxidized grape seed oil can be used for the synthesis of biobased polyols and its further application on the synthesis of polyurethane compounds.

“…The potential of Vernonia galamensis as a seed source of oil with inherent usefulness because of its oxirane content has been considered recently from both botanical and chemical viewpoints [12]. The vernolic (76%), oleic (4%) and linoleic (13%) acid levels in Vernonia galamensis oil represent additional epoxidizable unsaturation, so that fully epoxidized VO could have an oxirane value near 10% [13].…”

Abstract:In this study epoxidized vernonia oil (EVO) was synthesized by the epoxidation of vernonia oil using peroxyformic acid, formed in situ by the reaction of hydrogen peroxide and formic acid in the presence of an acidic ion exchange resin (Amberlite IR-120 hydrogen form) as the catalyst. This method of epoxidation has resulted in product with about 78% conversion. Acid exchange resin catalyzed epoxidation reactions are found to be promising in minimizing oxirane ring opening.
