  • Which is better des02 or des06 for epoxidation of soybean oil?
  • In presence of DES02, highest epoxy yield and selectivity of ESO were found compared to DES06 and the mechanism of double bond conversions of soybean oil during epoxidation was shown as Fig. 2. During reactions, hydrogen ions (H +) were effectively released from DES and bound with peroxy-formic acid.
  • What is epoxidation of soybean oil?
  • In the case of epoxidation of soybean oil, the formation of the epoxide functional groups is formed on a double bond that is located between two methylene groups in the fatty acid chains. Moreover, the peak signals from ∼62.13 to ∼77.86 ppm indicated the complete conversion to double bonds.
  • How does epoxidation affect the pH of soybean oil samples?
  • The acidic protons released from DES02 and DES06 catalysts during soybean oil epoxidations were responsible for decreasing pH of the ESO samples (Khundamri et al., 2019). However, pHs of all washed ESO samples slightly increased compared to pH of all non-washed ESO samples.
  • Does epoxidized soybean oil have higher viscosity?
  • The higher viscosity was seen in all epoxidized soybean samples produced followed by non-washing neutralization process compared to the washing processes. This could be stated by hydrogen bonds being sufficiently weakened with the rise in viscosity (Sahoo et al., 2019). 3.1.3. FTIR analysis of epoxidized soybean oil
  • How is vegetable oil epoxidation promoted?
  • Vegetable oil epoxidation is promoted by deep eutectic solvents (DESs) catalysts. Bio-based epoxy resin film was developed with epoxidized soybean oil. Epoxidation products were identified by 1 H NMR. Highest epoxy yield produced with choline chloride–oxalic acid solvent.
  • Can deep eutectic solvents dissolve soybean oil and hydrogen peroxide?
  • There are many different types of deep eutectic solvents. However, in this study, two deep eutectic solvents (DESs) as catalysts were chosen and prepared to dissolve soybean oil and oxidant, hydrogen peroxide, effectively due to their right combination of viscosity, polarity, and sustainability.
