| titleOfInvention | Method of adjusting alkylene oxide |
| abstract | (57) [Summary] (1) Optionally, contacting a metal hydroxide or oxide with chlorine to form a metal hypochlorite solution; (2) at least 80 based on hypochlorite. Contacting chlorine with a solution of a metal hypochlorite at a temperature of less than 60 ° C. and a pH of less than 5.5 with sufficient micromixing to obtain the product hypochlorous acid in mol% yield. (3) Step of separating at least a part of hypochlorous acid from an aqueous metal chloride solution of hypochlorous acid called chloride chloride brine, in which case at least 30 mol% of hypochlorous acid is in a liquid phase Solution is desorbed into the vapor phase in equilibrium of hypochlorous acid and dichlorine monoxide from the solution of the vapor stream as droplets having a volume median diameter of less than 500 microns. Spray into; (4) distill residual liquid phase Step of obtaining additional vapor of hypochlorous acid and dichlorine monoxide; (5) Absorption of hypochlorous acid and dichlorine monoxide in low chloride water to produce low chloride hypochlorous acid aqueous solution And (6) a continuous method using a continuous stirred tank reactor for maintaining a uniform steady-state HOCl concentration of 0.2% by weight or less in the reactor, using a low chloride hypochlorous acid aqueous solution as an olefin. Contacting to form the corresponding olefin chlorohydrin; (7) optionally contacting the olefin chlorohydrin with a base to form the corresponding alkylene oxide and salt solution; and (8) optionally salt Separating the alkylene oxide from the solution; (9) optionally chlorine from the chloride brine obtained from at least one of step 3 or step 4 by contacting the chlorate with an acid to convert it to chlorine. Step retrieve the salt; a and (10) optionally including the step of at least 1 Tsueto recirculation step 1 or step 4 chlorate, process for the preparation of an alkylene oxide. By the process according to the invention, alkylene oxides are obtained in particularly high yields, substantially without the formation of by-products. |
