    摘要： This invention is a process for preparing chlorohydrins by reacting a chlorinating species, such as hypochlorous acid, with at least one unsaturated organic compound, such as propylene or butylene, at a pH of greater than 6.0. The chlorinating species is formed in a first step by reacting a source of chlorine, such as Cl.sub.2 gas, with an aqueous pH adjusting source, such as aqueous NaOH.

    摘要： A process of preparing alkylene oxides comprises steps of: (1) optionally forming a hypochlorite solution; (2) contacting chlorine with a solution of a hypochlorite below about 60.degree. C., and a pH of less than about 5.5, with sufficient micromixing to achieve a product hypochlorous acid in a yield of at least about 80 percent; (3) separating at least a portion the hypochlorous acid from an aqueous metal chloride solution wherein the solution is sprayed as droplets; (4) distilling the remaining liquid phase; (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 to form a olefin chlorohydrin; (7) optionally contacting the olefin chlorohydrin with a base to form a 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 by contacting the chlorates with acid to convert the chlorates to chlorine; and (10) optionally recycling the chlorine. The process yields particularly high yields of the alkylene oxide without substantial production of by-products.

    摘要： Olefin is reacted with alkyl hypochlorite and water to produce an effluent containing the chlorohydrin and alkanol. An organic solvent is employed to extract the alkanol and chlorohydrin from the aqueous effluent, followed by saponification with base to produce olefin oxide. Olefin oxide is separated from the saponification effluent, followed by separation of an organic phase of the organic solvent, and an aqueous phase, which contains the alkanol. The aqueous phase containing alkanol, is chlorinated to produce the alkyl hypochlorite, with the organic phase being recycled to the extraction. The process is preferably integrated with the electrolytic production of chlorine.

    摘要： Olefin oxide is produced by reacting chlorine, obtained from an electrolysis cell, with a tertiary alkanol and an aqueous solution, containing sodium hydroxide and sodium chloride, obtained from the cathode of an electrolysis cell, to produce a tertiary alkyl hypochlorite. The hypochlorite is then reacted in a chlorohydrin reactor with an olefinically unsaturated compound and water, essentially free of chloride ions, to produce the corresponding chlorohydrin. The chlorohydrin is recovered and saponified with cell liquor, containing sodium hydroxide and sodium chloride, obtained from the cathode compartment of the cell to produce the olefin oxide.
