Abstract

Abstract Peracetic acid is one of the most essential organic solvents used in many chemical, pharmaceutical, food industries so on. There is an increasing demand for peracetic acid due to its versatile oxidative property. A continuous flow microstructured reactor techniques have been efficiently employed for the formation of peracetic acid using a homogeneous catalyst (sulfuric acid). In the experiments, the formation of peracetic acid was carried out at different molar ratios, three different configurations of microreactors, catalyst concentration and temperature. Three different configurations of a serpentine capillary microreactor, Corning® Advanced FlowTM Reactor, and helical capillary microreactor were compared for the formation of peracetic acid. Among these three microreactors, helical capillary microreactor has shown the maximum conversion of acetic acid in lesser time. The reaction is slow because the equilibrium reaches within 9 minutes at 60 °C and 12 mol % catalyst in 13.25 mm radius of curvature microreactor with the maximum concentration of peracetic acid achieved (3.751 mol/L (XAA = 62.21%)). The kinetic expressions of peracetic acid formation and hydrolysis were developed and the constants of the kinetic model were calculated. The activation energies (Ea) of peracetic acid formation and hydrolysis were 45.536 and 49.236 kJ/mol respectively. The equilibrium constant (Ke) was determined as 2.971, 2.838, 2.711, 2.590 and 2.475 at 20, 30, 40, 50 and 60 °C respectively.
