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

Abstract

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.

In situ epoxidation of canola oil via peracetic acid mechanism-optimization and kinetic study

“…The procedure in MATLAB does not take into account the heat loss and heat transfer during the reaction, so the numerical simulation is the best choice. 27 However, chemical reactions in the real world are complex and can be influenced by various factors that are not captured in a simulation. For example, impurities in the reactants, variations in the reaction conditions or non-ideal mixing can influence the actual reaction kinetics and lead to differences between the simulated and experimental results.…”

Synthesis of bio-polyol from epoxidized palm oleic acid by homogeneous catalyst

“…With a greater catalyst, the polyol-forming reaction between two or more reactants occurs more quickly. 23 By using 0.7 g of sulphuric acid as a catalyst in the production of polyol, the time taken to produce the polyol is decreased. Besides that, the percentage of production of bio-polyols is high because RCO was low compared to 0.5 g catalyst of sulphuric acid.…”

Recent advances of ring opening of epoxidation of palm oil derived from oleic acid via in situ hydrolysis under moderate temperature

“…In order to identify potential issues and develop strategies to overcome, the reaction kinetics change will help in the process of identifying as the process is being scaled up. 19 Kinetic modelling of the epoxidation process is essential to predict the reaction kinetics at industrial scale and ensure the successful optimization and scaling-up of the process. Thus, production of DHSA with acid catalyst was applied in this study in order to address this problem.…”

“…However, laboratory scale reactions may not accurately reflect the kinetics of industrial scale reactions. In order to identify potential issues and develop strategies to overcome, the reaction kinetics change will help in the process of identifying as the process is being scaled up 19 .
