The Effects of Acid and Hydrogen Peroxide Stabilizer on the Thermal Hazard of Adipic Acid Green Synthesis

The synthesis of adipic acid, which is formed by the reaction cyclohexene oxidized hydrogen peroxide (H2O2), hazardous because highly exothermic nature this and H2O2 decomposition. objective comprehensive study was to investigate illustrate effects sulfuric acid (H2SO4) stabilizer (EDTA) on thermal hazard decomposition green also provided a reference reduce risk reactions. Various calorimetry techniques were carried out characterize behavior An HPLC device used yield conversion rate raw materials, H2O2. Meanwhile, density functional theory calculations performed understand mechanism associated energies catalyzed sodium tungstate dihydrate (Na2WO4·2H2O). Finally, combined with results, assessed using intrinsic control index method (ITHI). results show that addition H2SO4 EDTA can heat acid. increased. level stage A IV, remove more heat, it recommended enhance reflux cooling A. B I, very low no further measures could be taken.
