Highly production of dihydroxystrearic acid from catalytic epoxidation process by in situ peracid mechanism

Abstract

AbstractEpoxidized 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: = 0.046 mol·L−1·min−1, = 39.058 mol·L−1·min−1, = 2.789 mol·L−1·min−1, and = 0.0235 mol·L−1·min−1 for of dihydroxystearic acid production.
