Measurement and Correlation of the Solubility and Diffusion Coefficient for Oxygen and Chlorine in Basic Hydrogen Peroxide
Abstract
The reaction between chlorine (CI) and basic hydrogen peroxide BHP, a mixture of hydrogen peroxide (H2O2) and potassium hydroxide (KOH), is currently being utilized to provide a source of singlet delta oxygen for iodine chemical lasers. The byproducts of the reaction are potassium chloride (KCI) and water (H2O). Typically an excess of hydrogen peroxide is used. The physical solubilities and liquid diffusion coefficients of oxygen (O2) and C12 in BHP are important physicochemical parameters needed to model any generator designed to produce singlet delta oxygen based on the reaction between gaseous C12 and BHP solutions. The objective of this research is to measure and correlate the solubility and diffusion coefficient for oxygen and chlorine in aqueous alkaline hydrogen peroxide solutions, in the range of -20 to 20C. The solution of interest for this work is an aqueous solution of 5 molar potassium hydroxide and 8 molar hydrogen peroxide (5 M KOH, 8 M H2O2 and 30 M H2O). This concentration of solution could be achieved by adding solid KOH to a 33 percent (wt) solution of hydrogen peroxide. Keywords: Chemical reactions; Reaction kinetics; Henry's law.
