摘要: A method in the production of hydrogen peroxide by the anthraquinone process is described, in which method anthraquinone derivatives dissolved in a working solution are subjected alternatingly to hydrogenation and oxidation. To reduce the relative moisture in the working solution to a suitable level of 20-98%, preferably 40-85%, the working solution is dried prior to hydrogenation by contacting it with a gas or a gaseous mixture, the water vapor pressure of which is below that of the working solution. Suitable gases or gas mixtures are air or exhaust gases from the oxidation stage of the anthraquinone process.

摘要: Processes for the production of sulfamic acid by the reaction of urea, sulfuric anhydride, and sulfuric acid in (1) a two-stage process wherein the sulfuric anhydride used in the first stage at a temperature less than 50.degree. C. is dissolved in a halogenated fluorocarbon or a mixture of halogenated fluorocarbons having a boiling point of from 0.degree. to 50.degree. C. or (2) in a one-stage process at 60.degree. to 100.degree. C. with the sulfuric anhydride dissolved in a halogenated fluorocarbon or a mixture of halogenated fluorocarbons having a boiling point below 100.degree. C. at atmospheric pressure, the halogenated fluorocarbon serving to remove the heat generated by the exothermic formation of the sulfamic acid from the original reactants.
