“…•A number of peroxides can decompose violently in the presence of strong acids. 29 •Fe(II) salts react with even hindered peroxides to generate reactive radicals. In the case of strained peroxides, even traces of ferrous iron can lead to exothermic decomposition.…”

“…According to reports, acid has a significant effect on the thermal stability of certain substances. Chou et al 22 investigated the stability of tert-butyl hydroperoxide with HNO 3 and H 2 SO 4 , both of which have a significant influence on TBHP. Grewer et al 5 pointed out that the decomposition temperature of many energy-containing materials in sulfuric acid solutions decreases.…”

In this study, kilogram-scale synthesis of 2-ethylhexyl nitrate in a microreactor was reported. Using Box–Behnken experimental design, the effects of process parameters such as temperature, molar ratio, total flow rate, and mass fraction of sulfuric acid on the yield of the target product were systematically investigated. The experimental design was studied at four factors and three levels. The results revealed that the sulfuric acid mass fraction and temperature significantly affected the yield of the product. There was a good agreement between the experimental results and predicted results by the proposed regression model. Subsequently, the mixing effect of the liquid–liquid heterogeneous system in microreactor was simulated by using computational fluid dynamics. The results provide solid evidence that the microreactor has excellent mixing efficiency in mass and heat transfer compared with the conventional reactor. Consequently, based on the results of process parameter optimization, an enlarged microreactor was designed to intensify the preparation of 2-ethylhexyl nitrate by a throughput of 16 kg/h.
