摘要： Calcium hypochlorite compositions useful as bleaching agents and disinfectants are produced by the reaction of solid granular hydrated lime and a solid granular alkali metal hydroxide with chlorine gas. The process takes place in the absence of a solvent and produces dry, free-blowing Ca(OCl).sub.2 compositions.

摘要： A process for preparing hypochlorous acid is described in which gaseous chlorine is reacted with an aqueous solution of alkali metal hydroxide in a finely divided mist form at an elevated temperature sufficient to prevent condensation of the gaseous product. Gaseous hypochlorous acid product is immediately separated from the resulting solid alkali metal chloride as it is formed and is then scrubbed with water to form an aqueous hypochlorous acid solution. This solution may be reacted with lime to produce calcium hypochlorite.

摘要： A method for preparing hydrazine and its compounds is described. Hypochlorous acid in a non-aqueous solvent is reacted with a carbonyl compound and with a nitrogen-contributing compound selected from the group consisting of ammonia, primary alkyl amines and mixtures of these. Hydrazine intermediates such as azines, hydrazones, and diazacyclopropanes are obtained and these may, if desired, be converted to hydrazine and its compounds, e.g., by hydrolysis.

摘要： A process for producing a chloroisocyanuric acid compound which comprises reacting cyanuric acid with a chlorinating agent consisting of an aqueous solution of hypochlorous acid substantially free of ionic impurities having a pH of less than about 2. The process produces chloroisocyanuric acid compounds with reduced volumes of effluent solutions and significantly reduced amounts of gas released during operation. The novel process for producing chloroisocyanuric acid compounds can employ solid forms of cyanuric acid as a reactant.

摘要： A process for preparing hypochlorous acid in a sweep reactor is described in which gaseous chlorine is passed rapidly across the surface of an agitated aqueous solution of .[.alkali metal.]. .Iadd.sodium .Iaddend.hydroxide at a reduced temperature. The resulting gaseous product mixture of hypochlorous acid, chlorine monoxide, and unreacted chlorine is conveyed from the reactor to a suitable scrubber to produce an aqueous hypochlorous acid solution.The aqueous reaction product of the sweep reactor is a suspension of .[.alkali metal.]. .Iadd.sodium .Iaddend.chloride in .[.alkali metal.]. .Iadd.sodium .Iaddend.hypochlorite, which is withdrawn and filtered to separate the solid. The clarified aqueous solution of .[.alkali metal.]. .Iadd.sodium .Iaddend.hypochlorite is reacted with the aqueous hypochlorous acid solution from the scrubber, chlorine and lime to form an aqueous slurry of calcium hypochlorite. This slurry may be granulated by the spray graining technique, for example, to produce strong rounded granules of calcium hypochlorite.
