Abstract
- Based on the Prileschajet reaction, formic acid (FA), hydrogen peroxide (H<subscript>2</subscript>O<subscript>2</subscript>) were selected as the oxidants and sulfuric acid (H<subscript>2</subscript>SO<subscript>4</subscript>) as the catalyst to establish the reaction model. 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. Consequently, a mathematical model of quasi-homogeneous system was established to describe the epoxidation process of SBO. Although the rate constants indicated that the formation of PFA was a decisive step of the whole system, PFA still exists as an intermediate in the system. Furthermore, the activation energy of PFA decomposition indicated the temperature sensitivity of PFA, making it prone to easy decomposition. This strongly suggests that the decomposition of PFA and its subsequent consequences are not to be treated as negligible phenomena. [ABSTRACT FROM AUTHOR]
