Definitions

  • the literature also contains the information that poor quality organobentonites can also be produced in the kneader by directly reacting the solid starting materials bentonite with N, N-dialkyldimethylammonium chloride.
  • the products obtained in this way are used in particular as thixotropic agents for a wide variety of purposes and have so far proven themselves.
  • a major disadvantage of these thixotropic agents and the by-products formed during their production is their very poor biodegradability. This also poses corrosion risks in many applications Presence of, albeit seemingly small amounts, chloride ions, which cannot be removed even with considerable washing effort.
  • the commercial forms of N, N-dialkyldimethylammonium chloride contain up to 15% 2-propanol, which, when used to produce organobentonites, entails additional risks and environmental problems.
  • the commercial products Noxamium 91, 920 and 960 contain certain amounts of 2-propanol. It is possible to remove this 2-propanol beforehand, for example by distillation. The reaction described above is still the same. Completely 2-propanol-free end products are thus obtained.

Abstract

L'invention concerne un agent hydrophobe à action rhéologique à base d'argiles ou de minéraux argileux échangeurs d'ions. L'agent hydrophobe selon l'invention contient comme cations imperméabilisants du N,N-di(acyloxy-2-éthyl)-N-hydroxy-2-éthyl-N-méthylammoniumméthosulfate, -méthophosphate ou diméthophosphate. On obtient, à partir de bentonites et de ces cations, des agents thixotropes hydrophobes sans chlorure, utilisables dans des produits techniques, cosmétiques et médico-pharmaceutiques.
