Nowadays, epoxidized vegetable oils are of major significance since they are derived from renewable and sustainable natural resources and are eco-friendly. Epoxide is a crucial chemical precursor to produce alcohols, glycols, and polymers such as polyester and epoxy resin. Oleic acid’s long alkyl chain including an unsaturated double bond (C=C) makes it an appealing fatty acid for producing eco-friendly epoxide. The epoxidation of unsaturated fatty acid was accomplished by generating performic acid in situ to yield epoxidized oleic acid. The result of this reaction will be dihydroxystearic acid (DHSA). DHSA is one of the chemical precursors used to manufacture cosmetics. The optimal level of epoxidized unsaturated oleic acid was 82%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
