Epoxidized oleic acid is often regarded as a high value oleochemical due to the wide range of industrial applications including cosmetics, personal care and pharmaceutical products. Epoxidized oleic acid also extensively chosen by industry due to its advantages on the good performance as intermediate chemicals and can be obtained from renewable sources. Synthesis and physicochemical properties of oleic acid palm oil was analyzed for further reaction of epoxidation. In this study, the epoxidation of oleic acid was investigated with performic acid generated in situ from hydrogen peroxide in H2O2 (30%) with formic acid. The characterization of oleic acid through iodine value, viscosity, acid value, saponification number and refractive index were 130, 146. 190.0, 206.1 and 1.47 respectively. On the other hand, the characterization of epoxidized oleic acid were 109.8, 156, 192.6, 219.9 and 1.38 of the same analysis. The chemical structures of the products were confirmed by 1H-NMR and 13C-NMR spectral analysis. © 2019 Published under licence by IOP Publishing Ltd.
