Abstract

1320200 Non - aqueous H 2 O 2 solutions DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 7 Oct 1970 [10 Oct 1970] 47583/70 Addition to 1279302 Heading ClA Non-aqueous solutions of hydrogen peroxide are obtained from a working solution containing the latter and obtained after the oxidation stage of the anthraquinone process, by means of a stripping distillation under reduced pressure using the vapours of an organic solvent comprising allyl acetate; or an ester of an aliphatic or cycloaliphatic alcohol with a fatty acid of the formula wherein R<SP>1</SP> is C 1-3 alkyl and R<SP>2</SP> and R<SP>3</SP> are C 1-2 alkyl; or an aliphatic or cycloaliphatic C 4-10 ether; or an aliphatic or cycloaliphatic C 3-7 ketone; or a mixture of at least one carboxylic acid, ester or alcohol with at least one hydrocarbon or hydrocarbon fraction of boiling point up to 160‹ C. as the stripping agent. Preferred stripping agents include the methyl, ethyl, propyl or butyl esters of trimethylacetic acid and di-n-propyl ether and when the stripping agent includes a hydrocarbon or a hydrocarbon mixture of boiling point up to 160‹ C. this preferably amounts to not more than 80% by weight of the agent.
