Abstract
In the green synthesis reaction of adipic acid, the oxidant H<sub>2</sub>O<sub>2</sub> undergoes exothermic decomposition easily and the high exothermic amount of the reaction can easily lead to thermal runaway. This study carries out calorimetric experiments on the green synthesis reaction of adipic acid, studies the effect of the stabilizer ethylenediaminetetraacetic acid (EDTA) on the safety of the synthesis reaction, and further explores the effect of EDTA on the Na<sub>2</sub>WO<sub>4</sub>-catalyzed decomposition reaction of H<sub>2</sub>O<sub>2</sub> under the conditions of continuous flow, and develops the microchannel continuous flow process of green synthesis of adipic acid containing EDTA, in order to provide theoretical support for the improvement of intrinsic safety of green synthesis of adipic acid.
