Kinetics of the Chlorine-Alkaline Peroxide Reaction
Abstract
This report covers research into the kinetics of the liquid phase reaction between chlorine and basic hydrogen peroxide (BHP) to produce singlet delta oxygen. The accepted mechanism for this reaction is given in three steps. The second step involves only a proton transfer and is expected to be much faster than the other two steps. The focus of this research was to measure (reaction rate constants) and k(3). Gas absorption measurements of chlorine in BHP in a laminar liquid jet absorber were carried out over the temperature range 1.8 to 8.9 C to determine k(1). The experimental data, obtained in the second- order kinetic regime, were interpreted using the penetration theory model. The k(1) measured is significantly lower than that estimated from previous work. Gas absorption measurements in a stirred cell absorber determined k(3). However, since this third step in the mechanism appears to have such fast kinetics, only a lower bound was determined fore this rate constant. At 0 C, the data indicate that k(3) > 500 l/s. (JG)
