原始语种摘要: Abstract(#br)Vernonia galamensis is a native weed of Ethiopia containing high concentration of naturally epoxidized oil (glyceryl trivernolate) in its seeds, which could be used as a potential substitute for currently used epoxy oils. Apart from an epoxy group, vernolic acid contains a double bond that could be further epoxidized yielding a low viscosity, high oxirane, non-edible oil. Epoxidized vegetable oils are usually produced at industrial scale mainly by the peracid process. Soluble mineral acids are essential for this process but these acidic components lead to several drawbacks. Our study deals with a solvent free epoxidation of vernonia oil using heterogeneous catalysts. Ordered mesoporous materials are good candidates as catalysts for epoxidation reactions of large molecules...
