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.

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.

Abstract: Process for the preparation of saturated aqueous solution of chlorite salts by the controlled reaction of chlorine dioxide with a reducing agent under reduced pressure to form chlorous acid. The chlorous acid is reacted with an aqueous solution of base to form an aqueous solution chlorite salt and the aqueous solution is recycled through the process. The process is rapid, economical and is conducted in a generator which is significantly smaller than equipment currently used for production of chlorite salts.

Abstract: Process for the generation of chlorine dioxide by the essentially instantaneous reaction of a relatively concentrated aqueous solution of a metal chlorite and an oxidizing agent, preferably gaseous chlorine. The reaction is carried out in a generator having a mix and dwell premix chamber interconnected with a source of vacuum, preferably a venturi. The relatively concentrated aqueous metal chlorite solution and the oxidizing agent are allowed to mix and react in the premix chamber prior to any dilution as, for example, by water or other fluid flowing through the venturi eductor to deliver the generated chlorine dioxide to storage or utilization. When the oxidizing agent is chlorine, it is preferred for the chlorine stream to contain some bleed water in an amount below that which would significantly dilute the reactants and thereby have a quenching effect on the reaction. The presence of bleed water prevents a buildup of metal chloride on the chlorine inlet to the premix chamber.

Abstract: A dry composition for the sustained, controlled production of gaseous chlorine dioxide comprising a dry, inert diluent; a metal chlorite selected from the group consisting of alkali metal chlorites and alkaline earth metal chlorites; and a dry agent capable of reacting with a metal chlorite in the dry state to produce chlorine dioxide, said agent being selected from the group consisting of dry oxidizing agents and dry acids. The composition of the invention is manufactured using solely dry constituents, thereby obviating an intensive drying step and resulting in substantial savings as well as simplifying the manufacturing process. The compositions of the invention find particular utility in applications involving the controlled generation of chlorine dioxide for a sustained period of time for the preservation of boxed fruits and vegetables during transportation or in deodorizing enclosed spaces such as refrigerators or lockers.

Abstract: A foam generating and distributing manifold device for generating and transporting foam cleansing and sanitizing agents having a manifold chamber with a centrally disposing frothing tube to generate foam which migrates upwardly within the chamber to a plurality of annularly disposed egress ports through which foam is distributed to a series of substantially equidistant supply conduits thereafter migrating to a distribution manifold which distributes the foam evenly upon, for example, conveyor belts used in food processing or the like.
