Definitions

  • the invention relates to a process for the preparation of flowable phthalimidoperoxyhexanoic acid-containing suspension and their use for the preparation of liquid detergents or cleaners.
  • Phthalimidoperoxyhexanoic acid is known, for example, from European patents EP 0 349 940 and EP 0 325 328. Their use in liquid washing or cleaning agents is described, for example, in European patent applications EP 0 442 549, EP 0 477 190, EP 0 484 095 or EP 1 010 750 or international patent applications WO 00/27960, WO 00/27971 or WO 00 / 29536 known. In the context of its production from aqueous systems, it normally accumulates in relatively large crystals which can cake together and which is commercially available as so-called "wet cake".
  • European Patent Application EP 0 890 635 recommends milling phthalimidoperoxyhexanoic acid in acidified water, which may also comprise defoamer, anionic surfactant, nonionic surfactant, hydrogen peroxide and / or inorganic salts.
  • European patent application EP 1 074 607 proposes to stabilize water-based dispersions of phthalimidoperoxyhexanoic acid by adding certain polymers.
  • the subject of the patent is a process for preparing a flowable suspension containing phthalimidoperoxyhexanoic acid by grinding phthalimidoperoxyhexanoic acid in alcoholic slurry.
  • the grinding can be carried out in conventional Najimahlvorraumen.
  • the grinding is preferably carried out with the aid of a toothed disc or a ball mill.
  • the grinding is preferably carried out until the average particle size (d 50 , determinable with a laser diffraction spectrometer) of phthalimidoperoxyhexanoic acid in the range of 10 .mu.m to 40 .mu.m, in particular from 12 .mu.m to 30 .mu.m.
  • the grinding is carried out until the size of at least 90% of the particles (d 90 , determinable also with a laser diffraction spectrometer) of phthalimidoperoxyhexanoic acid is less than 80 ⁇ m, in particular less than 50 ⁇ m. In a grinding process, it goes without saying that you assume a coarser quality.
  • wet cake which can easily contain particles up to 1 mm, or also by drying and optionally granulation of particles produced therefrom. Any adhering water need not be removed, but may be incorporated into the alcoholic slurry, in which case the alcohol component of the alcoholic slurry must be correspondingly water miscible.
  • the alcohol component of the alcoholic slurry is liquid at the grinding temperature and the phthalimidoperoxyhexanoic acid is substantially insoluble in it.
  • substantially insoluble is to be understood as meaning that the phthalimidoperoxyhexanoic acid in the alcohol component dissolves at most 10 times better, preferably at most 2 times better and more preferably no better than in water.
  • the grinding temperature is preferably at room temperature, but it may also be higher because of the energy input during the grinding process, but should remain below the boiling point of the alcohol at atmospheric pressure.
  • the C 1 to C 3 alcohols having up to 3 OH groups and mixtures thereof are suitable.
  • the alcohol is selected from the group comprising ethanol, propanol, isopropanol, ethanediol, 1,2-propanediol, glycerol and mixtures thereof.
  • the content of phthalimidoperoxyhexanoic acid in the alcoholic slurry is preferably in the range of 10 wt% to 90 wt%, more preferably 50 wt% to 85 wt%.
  • Flowable, non-sedimenting suspensions of phthalimidoperoxyhexanoic acid in the alcohol component are obtained in the manner described. Under flowable is understood that it at least partially flows out of an open vessel with appropriate inclination under the action of gravity and can be pumped easily in the context of their industrial processing.
  • a suspension obtainable by the process according to the invention is preferably used for the preparation of liquid detergents or cleaners.
  • a bleach-containing liquid washing or cleaning agent containing a suspension obtainable by the process according to the invention may be aqueous or substantially anhydrous and contain all other customary ingredients of such agents in addition to the suspension obtainable by the process according to the invention, unless they are in an unreasonably negative manner with the Phthalimidoperoxyhexanklare interact.
  • Such an agent preferably has an acidic pH which is in particular in the range from pH 2.5 to pH 6.5, preferably in the range from pH 3.5 to pH 5.5, and optionally adjusted by the presence of system-compatible acids may have been.
  • the phthalimidoperoxyhexanoic acid also remains sedimentation-stable in the liquid detergents or cleaners by the process according to the invention.
  • ingredients of such detergents or cleaners in the same alcoholic slurry can be ground simultaneously with the phthalimidoperoxyhexanoic acid, if they are in the alcoholic component in Slurry the presence of the phthalimidoperoxyhexanoic acid and mill it to the same particle size as the phthalimidoperoxyhexanoic acid.
