“…The kinetic model of the epoxidation process and epoxide ring degradation can be developed based on the following rate constants: k 11 , k 12 , k 2 , and k 3 . The following rate equations were modeled, and the set of simultaneous differential equations is given as Equations (7)(8)(9)(10)(11)(12)(13). Figure 1 shows the flow chart of the procedure used to determine the rate constants.…”

“…, 12 the Prileshajevepoxidation process is the initial conventional process used for the industrial production of epoxidized vegetable oils, in which peracids such as peracetic acid or performic acid are primarily used as the oxidizing agent. 13 Zeolite is a heterogeneous catalyst that is suitable in aqueous hydrogen peroxide, which will reduce acidity of epoxide yield. The mechanism of epoxidation preparation comprises three steps along with a parallel decomposition reaction.…”

Epoxidized vegetable oils are great concern as they are obtained from sustainable, and renewable natural resources. The epoxidation of palm oil-derived oleic acid was carried out by using in situ generated performic acid to produce epoxidized palm oil-derived oleic acid. The maximum conversion of palm oil-derived oleic acid into oxirane was 86% by applying the in situ peracid mechanism. Based on the Fourier-transform infrared spectrum, the hydroxyl group was observed within a wavenumber range of 1210-1320 cm À1 . Last, a mathematical model was developed using Runge-Kutta method and after 100 iterations, the reaction rate parameters were obtained as follows: k 11 = 0.046 molÁL À1 Ámin À1 , k 12 = 39.058 molÁL À1 Ámin À1 , k 2 = 2.789 molÁL À1 Ámin À1 , and k 3 = 0.0235 molÁL À1 Ámin À1 for of dihydroxystearic acid production.
