Abstract
A method of preparing chlorine dioxide in a non-aqueous liquid is disclosed. An aqueous solution of chlorine dioxide is mixed and agitated with a non-aqueous liquid. The chlorine dioxide is extracted into the non-aqueous liquid. In a preferred embodiment, an aqueous chlorite solution is added to a quantity of non-aqueous liquid. Acid is added to the aqueous phase to generate chlorine dioxide. The phases are vigorously agitated to extract the chlorine dioxide into the non-aqueous phase. High concentrations of very pure chlorine dioxide are obtainable. In another preferred embodiment, chlorine is prepared in a non-aqueous liquid and is mixed and agitated with an aqueous chlorite solution. Separation of the aqueous and non-aqueous phases provides pure solutions of chlorine dioxide in the non-aqueous liquid. Very pure aqueous solutions of chlorine dioxide are prepared by mixing and agitating non-aqueous solutions of chlorine dioxide with water. A reactant useful in oxidation, synthesis, disinfecting and sterilizing comprising chlorine dioxide dissolved in a non-aqueous liquid is disclosed.
