“…According to Santacessaria et al, 17 and the results show that the reaction profile is similar as that for the homogeneous catalyst. The only difference is that the RCO is slightly different from that for the homogeneous catalyst by 5%-8%.…”

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.

“…49 Although the synthesis of percarboxylic acids is generally performed by using a mineral acid catalyst, performic acid may be formed thermally, without any catalyst. 52 Formic acid was therefore continuously mixed with a stream of aqueous H 2 O 2 solution in the presence of an appropriate aldehyde, whereby the oxidizing agent performic acid was formed and consumed safely within the closed environment of a heated reaction coil. The oxidation of 3-phenylpropionaldehyde to 3-phenylpropanoic acid was selected as model reaction for a feasibility study and parameter optimization (Figure 1A).…”

“…It is known that performic acid is susceptible to decomposition into carbon dioxide, water, and oxygen even at room temperature after a certain time. 56 Upon heating at temperatures of >50 °C, the rate of the decomposition is increased drastically, 49,50,52,57 and at temperatures of >80 °C it may even explode at certain concentrations. 43 Under optimized flow conditions, only 10% excess of performic acid was required to achieve the quantitative oxidation of the model substrate.…”

“…However, under conditions sufficient for performic acid generation, peracetic acid formation proved incomplete as indicated by significantly lower product yields (Table 2). Gratifyingly, by employment of catalytic amounts of H 2 SO 4 , 52 peracid formation and the yield of the oxidation reaction could easily be enhanced. The best results were achieved with 3 wt % of H 2 SO 4 , which finally furnished quantitative and selective formation of the desired carboxylic acid.…”

The oxidation of aldehydes is one of the most prevalent methods for the synthesis of a diverse range of carboxylic acids. We herein present a performic acid generator and its application for aldehyde oxidations under continuous flow conditions. Low molecular weight performic acid, an environmentally benign and inexpensive oxidant, was readily formed in situ from formic acid and hydrogen peroxide. The safety hazards typically encountered when manipulating this potentially explosive reagent were eliminated, while at the same time a clean and efficient access to valuable carboxylic acids was ensured. By taking advantage of concentrated or even neat aldehyde streams, the amount of organic solvents utilized, and thus waste formation, was successfully minimized as demonstrated by E-factors in the range of 5−18. The process proved applicable for a wide range of aromatic as well as aliphatic aldehydes, while its synthetic utility and stability were corroborated by scale-out experiments leading to multigram-scale syntheses.

Peroxypropionic acid (PPA) is an important organic chemical compound. Due to its versatile oxidizing properties, it is used in the oil, chemical and other industries. In this article, an attempt was made for the production of PPA in a Teflon helical capillary microreactor without and with homogeneous catalyst. The article reports the perhydrolysis of PPA with the effect of various parameters such as concentration of hydrogen peroxide, molar ratio of reactants, radius of curvature of the microreactor, concentration of catalyst and temperature. The reaction is slow, as the PPA equilibrium was found to be reached within 10 min at a temperature of 50 °C and at 10 mol % catalyst loading based on propionic acid. The reaction was carried out in 13.25 and 23.25 mm radius of curvature of the microreactor in which 4.0375 and 3.488 mol/L concentrations of PPA respectively were obtained at 50 ºC and 10 mol % catalyst. It indicates that as radius of curvature decreases, better mixing was provided among the reactants for the reaction to give enhanced yield and selectivity. From the experimental data and the kinetic expressions, the expressions of activation energies and reaction rate constants were determined. For PPA synthesis and hydrolysis, the activation energies were 43.897 and 20.658 kJ/mol respectively without catalyst, while the activation energies for both the cases were 42.314 and 17.514 kJ/mol respectively with catalyst of 10 mol% based on propionic acid. The dean number, curve tube friction factor and pressure drop also determined for the helical capillary microreactor.
