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

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: k(11) = 0.046 mol.L-1.min(-1), k(12) = 39.058 mol.L-1.min(-1), k(2) = 2.789 mol.L-1 .min(-1), and k(3) = 0.0235 mol.L-1.min(-1) for of dihydroxystearic acid production.

Automated summary

The epoxidation of palm oil-derived oleic acid using in situ generated performic acid achieved a conversion rate of 86%, with the hydroxyl group observed in the product based on Fourier-transform infrared spectrum analysis. A mathematical model was developed to determine reaction rate parameters for dihydroxystearic acid production.
