  • Aqueous solution for the chemical sterilization of packaging materials, process for its preparation and its use
    Patent number: 7776261
    Abstract: Aqueous solution suitable for the chemical sterilization of packaging materials, process for its preparation and its use Aqueous solution suitable for the chemical sterilization of packaging materials, comprising hydrogen peroxide and at least one foodstuff-compatible stabilizer. This solution but without the stabilizer has a maximum phosphorous content expressed as PO43 —of 10 mg/kg, and present a dry residue at 105° C. of at most 10 mg/kg. The same solution can be used as dip bath liquid in dip bath aseptic packaging processes and as well as spraying liquid in spray aseptic packaging processes.

  • Process for producing alkyltetrahydroanthrahydroquinones and working solutions containing them for producing hydrogen peroxide by the anthraquinone process
    Patent number: 5147628
    Abstract: A process is disclosed for preparing alkyltetrahydroanthrahydroquinones in a solvent system suitable for the production of hydrogen peroxide. The resulting alkyltetrahydroanthrahydroquinone solutions can be used directly as working solutions for preparing H.sub.2 O.sub.2 by the anthraquinone process. It is also possible, if desired, to isolate the alkyltetrahydroanthrahydroquinones from the solution, or to oxidize the alkyltetrahydroanthrahydroquinones with an oxygen-containing gas to the corresponding alkyltetrahydroanthraquinones, which can then be isolated.
