  • Which side reaction is most important in the epoxidation of soybean oil?
  • Author to whom correspondence should be addressed. The epoxide ring opening reaction (ROR) can be considered as the most important side reaction occurring in the epoxidation of soybean oil reaction network. This reaction consistently reduces the selectivity to epoxidized soybean oil (ESBO).
  • What is epoxidized soybean oil (SBO)?
  • As for process (B), soybean oil (SBO) rstly took place epoxidation to produce oil methyl esters (ESBOME). Direct transformation of epoxi-dized soybean oil to ESBOME is highly attractive due to the large amount of epoxidized soybean oil produced in oleochemical industry each year.
  • What is the process of epoxidation of soybean oil methyl esters (SBO)?
  • In process (A), soybean oil (SBO) took place transesterication with methanol to produce soybean oil methyl esters (SBOME) in the presence of strong bases (e.g. NaOH, KOH, CH3ONa) as catalyst at 60 –70 C,14 and then SBOME undergo epoxidation catalyzed by strong acids (e.g. H2SO4) at 4060 C in the presence of H2O2.15The whole process
  • What is the reaction mechanism of soybean oil?
  • Initially, the reaction mechanism of the system was explained by investigating the process conditions of soybean oil (SBO), and the results showed that the two-phase (oil–water) reaction system was similar to the quasi-homogeneous system.
  • Does oxirane ring opening reduce the selectivity of soybean oil epoxidation?
  • The selectivity of the soybean oil epoxidation is significantly lowered by the occurrence of some undesired side reactions characterized by the oxirane ring opening.
  • Why is the epoxidation of SBO complicated?
  • Because the reaction takes place in an emulsion system, the epoxidation of SBO with performic acid (PFA) as the oxygen carrier is complicated. SBO's epoxidation occurs primarily in the oil phase, and consequently mass transfer has an important influence on this process. The relevant reactions in the epoxidation of SBO are shown in Fig. 2.
