Definitions

  • the present invention relates to a process for producing a mixture of sodium silicates with a layer structure and a molar SiO2: Na2O ratio of 1.9: 1 to 20: 1, preferably from 3.5: 1 to 4.5: 1 and from at least one a salt that supports a washing or cleaning process and the use of this mixture.
  • Modern detergents are multi-component mixtures consisting of builders, cobuilders, a bleaching system and a stabilizer.
  • Sodium tripolyphosphate or zeolite A are used as builders, polycarboxylates as cobuilders, percarbonates or a mixture of perborates and tetraacetylethylene diamine (TAED) as bleaching systems and phosphonates as stabilizers.
  • TAED tetraacetylethylene diamine
  • a washing and cleaning agent can contain crystalline layered sodium silicate as a builder (cf. EP-PS 164 514).
  • layered silicates of particular interest which have the composition NaHSi2O5. x H2O and whose structure is derived from the Kanemit, for example NaHSi2O5, NaHSi2O5. H2O, NaHSi2O5. 3 H2O.
  • Kanemite can be obtained either from ⁇ -Na2Si2O5 or from ⁇ -Na2Si2O5 by treating with a water-methanol mixture at 100 ° C, then heating to 700 ° C for 24 hours and subsequent treatment with water.
  • a kanemite-like product is obtained in that ⁇ -Na2Si2O5 is slurried with water, the slurry is then filtered and the resulting solid is finally dried at 105 ° C.
  • Sodium peroxocarbonate hydrate which is used as a bleaching and oxidizing agent in detergents and cleaning agents, is obtained from aqueous solutions of sodium carbonate and hydrogen peroxide, sodium chloride, sodium polyphosphates or polyacrylates serving as salting-out and crystallization aids (cf. "Ullmanns Encyklopadie der Technische Chemie", 4 Edition, volume 17, page 734).
  • the mixture produced by the process according to the invention can be used as an agent for washing, cleaning and dishwashing, and for bleaching paper and cellulose.
  • the effect of the mixture according to the invention as a detergent, cleaning agent and dishwashing detergent is based on the layered molecular structure and the inherent pH of the hydrogen silicate contained in it, which causes the storage or precipitation of the alkaline earth metal ions contained in the water (softening of the water) becomes.
  • the mixture according to the invention can have a peroxide content of up to about 17% by weight.
