摘要： Described herein is a physiologically-balanced, acidic solution. Typically the solution is prepared by a chemical reactions or by the electrolysis of a solution s comprising a mixture of an inorganic salt to form a physiologically balanced solution. This invention also relates to methods for use of the solutions, including a specialized bandage which may be used in combination with the solutions, or optionally with other topically applied materials. A mixture of inorganic salts and, optionally minerals, is used in order to mimic the electrolyte concentration and mixture of body fluid in an isotonic state. The solution typically comprises of one halide salt of lithium, sodium, potassium, calcium, and other cations. Typically the halide is fluoride, chloride, bromide, or iodide, and most typically chloride. A typical electrolyzed solution of the present invention has a pH within the range of about 2 to about 5, an oxidation reduction potential within the range of about +600 mV to about +1200 mV, and hypohalous acid concentration in the range of about 10 ppm to about 200 ppm. The solution has bactericidal, fungicidal, and sporicidal properties. The composition of the invention is nontoxic and has antibacterial properties, and is useful in any application in which antimicrobial properties are desirable.

摘要： A process for producing hypochlorous acid by reacting an aqueous solution of an alkali metal hydroxide in droplet form with gaseous chlorine to produce hypochlorous acid vapor and solid alkali metal chloride particles in which the improvement comprises employing molar ratios of gaseous chlorine to the alkali metal hydroxide of at least about 22:1. The process achieves high yields of hypochlorous acid by minimizing side reactions including the formation of chlorate as an impurity in the alkali metal chloride particles produced. The hypochlorous acid solution produced contains from about 35 to about 60 percent by weight of HOCl, a dissolved chlorine concentration of less than about 2 percent by weight, and is substantially free of alkali metal ions and chloride ions.

摘要： Procédé de production d'acide hypochloreux consistant à faire réagir un hydroxyde de métal alcalin sous forme de gouttelettes avec du chlore gazeux pour obtenir de l'acide hypochloreux en phase vapeur ainsi que des particules solides de chlorure de métal alcalin, procédé dans lequel l'amélioration consiste à employer des rapports molaires de chlorure gazeux par rapport à l'hydroxyde de métal alcalin d'au moins 22/1. Ce procédé permet d'obtenir des rendements élevés en acide hypochloreux en minimisant les réactions secondaires comprenant la formation de chlorate à titre d'impureté dans les particules de chlorure de métal alcalin produites. La solution d'acide hypochloreux obtenue contient de 35 à 60% en poids, environ, de HOCl, une concentration pondérale en chlore dissous inférieure à environ 2%, et ne contient pratiquement pas d'ions métalliques ni d'ions chlore.

摘要： A method for preparing a stabilized antimicrobial hypochlorous acid solution by diluting an aged stock solution to provide a hypochlorous acid solution at a concentration of about 50 to about 7000 ppm at a pH range of about 2.8 to about 4.0. The antimicrobial hypochlorous acid solution maintains at least 75 percent of the available chlorine present over a period of about 6 months to about 12 months. The antimicrobial hypochlorous acid solution has medical applications in humans and veterinary practice, both prophylactic and therapeutic. The solution can also be used for non-medical applications in antisepsis and sterilization of surfaces.

摘要： A process of preparing alkylene oxides comprises steps of: (1) optionally contacting metal hydroxide or oxide with chlorine to form a metal hypochlorite solution; (2) contacting chlorine with a solution of a metal hypochlorite at a temperature below 60 °C, and a pH of less than 5.5, with sufficient micromixing to achieve a product hypochlorous acid in a yield of at least 80 mole percent based on hypochlorite; (3) separating at least a portion of the hypochlorous acid from an aqueous metal chloride solution thereof, hereinafter referred to as chloride brine, wherein the solution is sprayed as droplets having a volume median diameter of less than 500 micrometers into a vapor stream such that at least 30 mole percent of the hypochlorous acid is desorbed from a liquid phase into a vapor phase where hypochlorous acid and dichlorine monoxide are in equilibrium; (4) distilling the remaining liquid phase to obtain additional hypochlorous acid and dichlorine monoxide vapor; (5) absorbing the hypochlorous acid and dichlorine monoxide in low-chlorides water to produce a low-chlorides aqueous hypochlorous acid solution; (6) contacting the low-chlorides aqueous hypochlorous acid solution with an olefin in a continuous process using a continuous stirred tank reactor to maintain a uniform steady-state HOCl concentration in the reactor of 0.2 weight percent or less to form a corresponding olefin chlorohydrin; (7) optionally contacting the olefin chlorohydrin with a base to form a corresponding alkylene oxide and a salt solution; and (8) optionally separating the alkylene oxide from the salt solution; (9) optionally removing chlorates from the chloride brine from at least one of Steps 3 or 4 by contacting the chlorates with acid to convert the chlorates to chlorine; and (10) optionally recycling the chlorine to at least one of Steps 1 or 4. The process yields particularly high yields of the alkylene oxide without substantial production of by-products.
