Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
64 words
A method of producing a water soluble iodine concentrate consisting essentially of dissolving 100 parts by weight of iodine in at least about 37 parts by weight of dimethyl sulfoxide, and dissolving the resultant system in a water solution surfactant selected from the group consisting of anionic and nonionic surfactants in an amount sufficient effectively to enhance the solubility of said system in water.
Claim 2
Independent Claim
64 words
A method of producing a water soluble iodine concentrate consisting essentially of dissolving 100 parts by weight of iodine in at least about 37 parts by weight of dimethyl sulfoxide, and dissolving the resultant system in a water solution surfactant selected from the group consisting of anionic and nonionic surfactants in an amount sufficient effectively to enhance the solubility of said system in water.
Claim 3
Independent Claim
94 words
A method of producing an aqueous iodine solution consisting essentially of mixing iodine and dimethyl sulfoxide to form a first system in which the dimethyl sulfoxide is present in at least about 37% by weight of the iodine, mixing the first system with a water soluble surfactant selected from the group consisting of nonionic and anionic surfactants in an amount sufficient effectively to enhance the solubility of said system in water, to form a second system, and subsequently dissolving the second system in water in an amount sufficient to achieve a desired dilute solution.
Claim 4
Independent Claim
94 words
A method of producing an aqueous iodine solution consisting essentially of mixing iodine and dimethyl sulfoxide to form a first system in which the dimethyl sulfoxide is present in at least about 37% by weight of the iodine, mixing the first system with a water soluble surfactant selected from the group consisting of nonionic and anionic surfactants in an amount sufficient effectively to enhance the solubility of said system in water, to form a second system, and subsequently dissolving the second system in water in an amount sufficient to achieve a desired dilute solution.
Claim 5
Independent Claim
78 words
A method of producing a water soluble iodine concentrate at ambient temperature consisting essentially of mixing iodine with dimethyl sulfoxide to form a first fluid organic complex, the dimethyl sulfoxide being present in at least about 37% by weight of the iodine; and thereafter mixing said first fluid complex with a water soluble surfactant selected from the group consisting of nonionic and anionic surfactants in an amount sufficient effectively to enhance the solubility of said system in water.
Claim 6
Independent Claim
78 words
A method of producing a water soluble iodine concentrate at ambient temperature consisting essentially of mixing iodine with dimethyl sulfoxide to form a first fluid organic complex, the dimethyl sulfoxide being present in at least about 37% by weight of the iodine; and thereafter mixing said first fluid complex with a water soluble surfactant selected from the group consisting of nonionic and anionic surfactants in an amount sufficient effectively to enhance the solubility of said system in water.
