Kinetics of CH3COOOH Formation from CH3COOH + H2O2 Reaction in the Presence of H+ Ion

Abstract

Kinetics of peracetic acid formation in the reaction between acetic acid and hydro peroxide was investigated in this study. Experiments were conducted in a batch-reactor with a solution volume of 50 mL at 25 ± 1 ^oC. Concentrations of acetic acid and hydro peroxide are 10.5 M and 4.2 M, respectively.  The effect of H⁺ ion on the reaction was evaluated in the range from  0.036 to 0.72 M. The formation of peracetic acid was followed by iod - thiosulfate titration with starch indicator. Experimental data were analyzed using reversible first - order rate law to get reaction orders of H⁺ and H₂O₂ to be 1.
