Abstract
A method of preparing and storing a stable solution of chlorine dioxide in a non-aqueous, water-immiscible liquid. An aqueous solution of chlorine dioxide is vigorously mixed with a non-aqueous, water immiscible liquid and, in a single extraction, the chlorine dioxide is extracted into the non-aqueous liquid. The aqueous and non-aqueous phases are separated and the chlorine dioxide containing non-aqueous liquid is stored in a closed light-free environment. In an alternate embodiment, gaseous chlorine dioxide is introduced into the non-aqueous, water-immiscible liquid. Concentrations of 2,000 mg to 17,000 mg chlorine dioxide per liter are obtained. The chlorine dioxide in the non-aqueous liquid is stabilized for at least one month. A highly purified aqueous solution of chlorine dioxide is prepared by mixing the non-aqueous solution of chlorine dioxide with water and extracting chlorine dioxide into the water.
