Numerous academics worldwide are interested in utilizing waste as a resource to produce an epoxide. Epoxidation/ring‐opening of oxirane is a common method for producing polyols from vegetable oil. This study examined the effect of the catalyst type and loading on the ring opening of epoxide groups by utilizing performic acid generated in situ. The outcomes demonstrated that the zeolite catalyst at 0.2 g loading produced the highest conversion of oxirane (RCO%). The FTIR data showed that the epoxy ring group‘s location caused the hydroxyl group‘s (O−H) to be observed at 3100–3600 cm−1 in the placement of the epoxy ring group (C−O−C) at 1210–1250 cm−1. Finally, optimization and kinetic modeling using artificial neural networks, abbreviated as Neural Network, is a model of the human brain that is abstracted, simulated, and trained to obtain the value of R closest to 1.

“…Palm oil is extracted from the fruit of the oil palm tree (Elaeis guineensis). 1 It is rich in saturated and unsaturated fatty acids, including palmitic, stearic, oleic, and linoleic acids, which give palm oil its unique physical and chemical properties. In the non-food sector, palm oil is used in a range of industrial applications, such as the production of soap, cosmetics, and biodiesel.…”

Epoxidized oleic acid was considered a more sustainable alternative to traditional plasticizers such as phthalates, which have been linked to potential health and environmental hazards. This study aims to synthesize and characterize the formation of dihydroxystearic acid (DHSA) from the ring opening of epoxidized oleic acid. The optimal reaction parameters to produce DHSA were found using sulfuric acid as catalyst in which the maximum relative conversion was reached up to 86%. The detection of hydroxyl group was using Fourier Transform Infrared Spectroscopy. Then, a mathematical model was developed using MATLAB software, and as a result the kinetic model provided a good description of the reaction process, and it could be used to predict the behavior of the reaction under different conditions. Overall, the optimal reaction conditions and the maximum relative conversion of palm oleic acid to oxirane, are important contributions to the field of green chemistry.

“…14 These days there are many industrially applied, homogenous epoxidation process using in situ formed per carboxylic acid. 15 However, this process has low selectivity for epoxides and generates significant reactor corrosion. It is important to note, however, that the usage of acids, particularly those contained in synthetic zeolite, might lead to corrosion because synthetic zeolite produced oxidizing environment.…”

In recent years, there has been a growing demand for environmentally friendly epoxides made from vegetable oils. Therefore, the use of materials from renewable resources, was implemented in this study with natural zeolite as a catalyst being chosen over synthetic zeolite because synthetic zeolite mostly consists of strong corrosive materials. The aims of this research to determine the effect of catalyst concentration on the relative conversion of oxirane (RCO). RCO was the highest at 30 min of the reaction for sunflower oil, being 72% at 80°C using a 0.25 g concentration of catalyst. Meanwhile, for palm oil, the highest RCO was only 52% at 80°C. Lastly, MATLAB software was used to develop a mathematical model for determination rate constant. In this model, the Runge–Kutta method of the fourth order was combined with genetic algorithm optimization to for development of kinetic model that best fitted with the experimental data.
