FREMGANGSMAATE FOR KONTINUERLIG FREMSTILLING AV DIALKYLPEROKSYDIKARBONATER

摘要

The present invention provides a process for the continuous production of dialkylperoxydicarbonates of the general formula: (I) in which R stands for the same or different, straight-chained, cyclic or branched alkyl radicals containing 6 to 18 carbon atoms, by the continuous reaction of a chloroformic acid ester of the general formula: (II) wherein R has the above-given meanings, in an aqueous medium with hydrogen peroxide and an alkali metal hydroxide at a temperature of from -10 DEG C. to +50 DEG C. in at least two reaction zones connected in series and continuous isolation of the dialkylperoxydicarbonate formed from the solvent-free reaction mixture with the use of a centrifuge, wherein the reaction is carried out in the presence of a surfactant and the dialkylperoxydicarbonate formed is separated in molten form from the alkaline reaction mixture heated to or just above the melting temperature of the dialkylperoxydicarbonate.
