Definitions

  • Alkaline alumosilicates especially crystalline or amorphous zeolites, are becoming increasingly important as detergent builders.
  • these builders only reach in combination with other complexing agents for divalent cations such as. B. pentasodium triphosphate, NTPP for short, optimal washing properties.
  • B. pentasodium triphosphate, NTPP for short, optimal washing properties.
  • alkali alumosilicates are fine powder, there is great interest in non-dusting, free-flowing granules which contain both alkali alumosilicates and NTPP. These can then be added dry to the other detergent components without dust formation, hydrolysis of the triphosphate also being avoided.
  • DE-A-2 714 604 describes a granulate consisting of ion-exchanging alkali alumosilicate, a highly polymeric phosphate with a P 2 0 s content of 64-69%, and pentasodium triphosphate.
  • the high polymer phosphate is added to the granulation mixture in powder form in the form of alkali salts and in an amount of at least 5% by weight, based on the alkali alumosilicate used. The mixture is then granulated in the presence of water.
  • This method has the disadvantage that the water is bound by the NTPP so quickly that it is no longer able to dissolve enough polymer phosphate for better granulation. Therefore, either larger amounts of polymer phosphate and longer vellwell times are required, or more water has to be added, which means that the granules have to be subsequently dried at 50 ° C.
  • DE-A-2 756 732 describes a granulate which likewise consists of alkali alumosilicate and a partially or fully hydrated alkali polyphosphate.
  • This granulate is produced by spraying water in fine mists onto the powder mixture of the granulate components, with a maximum of 10% of the total amount of water being allowed to be added per minute, since otherwise too large granulate particles are obtained in addition to a high dust content. This process therefore harbors the danger of producing granules with a very broad grain spectrum which still have to be sieved afterwards.
  • DE-A-2 822 231 describes granules of hydrated pentasodium triphosphate and water-insoluble aluminosilicate ion exchange material. This is also produced by spraying water onto the powder mixture, the total amount of water used being at least that required to achieve a minimum hydrate water content of about 10% by weight in the sodium tripolyphosphate and a water content in the aluminosilicate ion exchange material of 1.8 to 13.5 mol water per mol aluminosilicate .
  • the strength of the granulate particles obtained in this way can still be improved, as will be shown below with reference to the invention.
  • the proportion of the partially or fully hydrated pentasodium triphosphate is 30-70% by weight and the proportion of the ammonium polyphosphate is 0.03 to 1.6% by weight. At least 10% by weight of the pentasodium triphosphate is present here tes as hexahydrate and at least 30 wt .-% of the aluminosilicate as hydrate with a maximum of 13.5 moles of water per mole of aluminosilicate.
  • spraying is preferably carried out on an intimate powdery mixture of 1 to 99% by weight of an anhydrous or optionally at most 5% by weight water-containing pentasodium triphosphate and 99 to 1% by weight of a powdered, anhydrous or optionally bound water containing aluminosilicate ion exchange material of the general formula in which Kat, Me, w, x and y have the meaning given, with vigorous mixing, an aqueous 0.5-20% by weight solution in a fine mist and granulates the mixture with partial or complete hydration of the pentasodium triphosphate or Aluminum silicate exchange material.
  • the powdery mixture can consist of 30 to 70% by weight of the pentasodium triphosphate and 70 to 30% by weight of the aluminosilicate, the latter, for example, a zeolite of the formula can be.
  • the pentasodium triphosphate is present as hexahydrate and at least 30% by weight of the aluminosilicate is present as a hydrate with at most 13.5 mol of water per mol of aluminosilicate in the finished granulate.
  • the mixture is generally sprayed with an aqueous 1-10% by weight solution of ammonium polyphosphate.
  • Products of the aforementioned formula composition are to be used as the aluminosilicate ion exchange material.
  • Zeolites such as e.g. Zeolite A. Because of their use as detergent builders, they are in very fine-particle form, for example with an average particle diameter of 3-5 ⁇ m.
  • the P 2 0 5 content of the ammonium polyphosphate used for the granulation is more than 69%, polyphosphates with a P 2 0 5 content of over 71% being preferred.
  • the process according to the invention can be carried out, for example, by first mixing the pentasodium triphosphate with the aluminosilicate material in a mixer and then spraying the aqueous ammonium polyphosphate solution onto the mixture via a nozzle.
  • the spraying can also be carried out, for example, in a rotary tube or on a granulating plate onto the premixed material. It is important to ensure that no more granulating liquid is sprayed on than is necessary for the complete hydration of the sodium triphosphate contained in the mixture.
  • a granulate produced in this way is not dusty, abrasion-resistant and stable in storage. It meets the requirements for further processing in detergents by dry admixing.
  • Example 2 The procedure was as in Example 1, but using a 4% aqueous APP solution.
  • the mixed granules obtained from sodium triphosphate and zeolite had the following properties:
