Abstract： Epoxidized soybean oil (ESO) was prepared with formic acid as oxygen carrier in a solvent-free system. The optimal production conditions of formic acid ESO were determined through orthogonal experiments. To further enhance the oxirane content and shorten reaction time, a small amount of sulfuric acid was added as catalyst. The results showed that when the mass ratio of soybean oil, formic acid, 30% hydrogen peroxide and sulfuric acid was 1:0.13:0.7:0.004, the oxirane content of product was 6.2% and the residual iodine value (IV) less than 6.0% after 3 h reaction at 65℃. The FT-IR, 1H-NMR and 13C-NMR spectra of the product were recorded in order to further characterize its chemical structure.
