Abstract: 1343052 Non-aqueous hydrogen peroxide solutions DEUTSCHE GOLD-UND SILBERSCHEIDEANSTALT 21 May 1971 [23 May 1970] 16188/71 Heading C1A [Also in Division B1] A non-aqueous solution of hydrogen peroxide is obtained by passing a working solution containing hydrogen peroxide obtained by the anthraquinone process through a film forming evaporator in the presence of the vapour of at least one organic solvent for hydrogen peroxide which is chemically stable under the process conditions and which boils at 30 to 180‹ C. at normal pressure, and thereafter condensing the vapour containing H 2 O 2 , produced in the evaporator by desorption of H 2 O 2 from the working solution, either by direct evaporation cooling with the liquid organic solvent or solvents used, preferably in supercooled form, or by a heat exchanger. The working solution may be preheated-before being passed to the evaporator and during evaporation, the organic solvent/s vapours may be guided in parallel current with or in counter current to the working solution. Alternatively, the vapour of the organic solvent/s may be produced in situ from the working solution in the evaporator. The desorption of H 2 O 2 is preferably carried out under a reduced pressure of 5 to 60 Torr. and the organic solvent/s used in the desorption are preferably carboxylic acids, esters, alcohols, ketones and ethers or mixtures of these or combinations with hydrocarbons.
