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−1. Last, a mathematical model was developed using Runge–Kutta method and after 100 iterations, the reaction rate parameters were obtained as follows: (Formula presented.) = 0.046 mol·L−1·min−1, (Formula presented.) = 39.058 mol·L−1·min−1, (Formula presented.) = 2.789 mol·L−1·min−1, and (Formula presented.) = 0.0235 mol·L−1·min−1 for of dihydroxystearic acid production. © 2021 American Institute of Chemical Engineers.
