Kinetics of CH3COOOH formation from CH3COOH + H2O2 reaction in the presence of H+ ion

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
