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.
A method of disinfecting and deodorizing an enclosed space consisting of placing in said enclosed space an effective amount of a dry composition for the sustained, controlled production of gaseous chlorine dioxide, said dry composition comprising (1) a dry, inert diluent, (2) a metal chlorite selected from the group consisting of alkali metal chlorites and alkaline earth metal chlorites, and (3) a dry agent capable of reacting with said metal chlorite in the dry state to produce chlorine dioxide, said agent being selected from the group consisting of dry oxidizing agents, dry acids, and combinations thereof.
A method of disinfecting and deodorizing an enclosed space consisting of placing in said enclosed space an effective amount of a dry composition for the sustained, controlled production of gaseous chlorine dioxide, said dry composition comprising (1) a dry, inert diluent, (2) a metal chlorite selected from the group consisting of alkali metal chlorites and alkaline earth metal chlorites, and (3) a dry agent capable of reacting with said metal chlorite in the dry state to produce chlorine dioxide, said agent being selected from the group consisting of dry oxidizing agents, dry acids, and combinations thereof;
A method of preserving boxed fruits and vegetables during the shipment thereof consisting of placing in the vicinity of said boxed fruits and vegetables a gas permeable container containing an effective amount of a dry composition for the sustained, controlled production of gaseous chlorine dioxide, said dry composition comprising (1) a dry, inert diluent, (2) a metal chlorite selected from the group consisting of alkali metal chlorites and alkaline earth metal chlorites, and (3) a dry agent capable of reacting with said metal chlorite in the dry state to produce chlorine dioxide, said agent being selected from the group consisting of dry oxidizing agents, dry acids, and combinations thereof.
