Definitions
- the present invention relates to hydrophobic, rheologically active products based on ion-exchangeable clays and / or clay minerals which contain ions with a hydrophobic effect.
- the invention further relates to processes for the preparation of these compositions and their use.
- Hydrophobic, rheologically active products based on ion-exchangeable clays and / or clay minerals are known as heology modifiers. So far, they have been produced by reacting ion-exchangeable clays and / or clay minerals, in particular bentonites, which contain montmorillonite or hectorite as main constituents, or attapulgites with quaternary ammonium salts. As quaternary ammonium salts, above all N, N-dialkyl-dimethylammonium chlorides are reacted in a mostly warm aqueous slurry of bentonite or attapulgite.
- the literature also contains the information that organobentonites of inferior quality can also be produced in the kneader by directly reacting bentonites 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 as such.
- a major disadvantage of these thixotropic agents and the by-products formed during their production is their poor biodegradability. corrosion risks are also caused in many applications by the presence of chloride ions, which cannot be removed even by considerable washing effort.
- typical commercial forms of N, N-dialkyldimethylammonium chlorides contain up to 15% 2-propanol, which, when used in the production of organobentonites, causes additional environmental problems.
- the object of the present invention is to provide hydrophobic, rheologically active products based on ion-exchangeable clays and / or clay minerals which are much more readily biodegradable, contain no chloride ions and, if possible, can also be prepared 2-propanol-free. If possible, they should be able to replace the previous products in all areas such as paints, varnishes, coating systems, construction technology, cosmetics, medical-pharmaceutical products, lubricants etc. without much effort.
- Rl and R4 can be chemically identical or different, can represent a hydrogen atom, a straight-chain or branched, cyclic or heterocyclic, unsubstituted or substituted, saturated or unsaturated hydrocarbon radical having 1 to 40 carbon atoms, where Rl is not necessarily via the COO group, but can be bonded directly to the nitrogen atom, R2 is a hydrogen atom, a short-chain hydrocarbon radical having 1 to 24 carbon atoms, which is optionally substituted by a hydroxyl group or an aromatic or heterocyclic group, R3 is a hydrogen atom, a straight-chain or branched, saturated or unsaturated hydrocarbon radical with 1 to 24 carbon atoms, Hi, represents a direct bond or is a straight-chain or branched, saturated or unsaturated hydrocarbon radical with 1 to 24 carbon atoms,
- Y ⁇ ⁇ an anion which does not corrode but has a protective effect on metals, with the exception of the N, N-di (acyloxy-2-ethyl) -N-hydroxy-2-ethyl, N-methyl ammonium methosulfates, -methophosphates and / or - dimethophosphate,
- the present invention thus relates to such hydrophobic, rheologically active products, with the exception of the N, N-di (acyioxy-2-ethyl) -N ⁇ bydroxy-2-ethyl, N-methyl ammonium methosulfates, methophosphates and / or dimethophosphates which are already the subject of unpublished PCT / EP00 / 01294.
- ion-exchangeable clays and / or clay minerals are bentonites, hectorites and / or attapulgites. Depending on their exchange capacity, they are reacted with the respective quaternary ammonium compound in a molar ratio of 1: 1.5 to 1: 0.1.
- both the cations in the exchangeable clays and / or clay minerals and the clays and clay minerals used can be varied within wide limits and nevertheless very useful hydrophobic, rheologically active products are produced which are capable of to solve the task.
- Bentonites are preferred as ion-exchangeable clays and / or clay minerals. Montmorillonite or hectorite-rich starting materials are used in particular, as well as attapulgite. Knowledge of the ion exchange capacity of the starting material in mmol / 100 g is essential. For complete conversion, the same molar amount of quaternary ester of the above formula is usually used in mmol. The molar ratio of both reactants can, depending on the desired end properties of the product, from 1: 1.5 (non-polar) to 1: 0.1 (strongly polar) can be selected. The resulting product is practically water-insoluble and generally contains, as a by-product of the reaction, the non-corrosive metal salts of the anions used, such as alkali and alkaline earth metal salts, which are formed by ion exchange.
- the non-corrosive metal salts of the anions used such as alkali and alkaline earth metal salts, which are formed by ion exchange.
- the soluble parts can also be washed out by the known wet process.
- the reaction product is separated from the mother liquor by filtration or centrifugation and, if necessary, washed with solvent or water.
- the water-containing filter cake is then subjected to drying, then crushed and ground.
- the phosphates, methophosphates or dimethophosphates or phosphonates proposed according to the invention and their homologues are e.g. B. producible by reacting the respective tertiary amine with trialkyl phosphite, for example trimethyl phosphites and subsequent oxidation to the phosphate.
- the methophosphates and dimethophosphates or the alkyl phosphates which are otherwise used have the advantage that they generally do not have to be washed out, since the production-related impurities do not trigger any risk of corrosion, but rather act as an adhesion promoter and as an anti-corrosion agent. They can be clearly seen on very smooth surfaces Improve the adhesion of a paint. In cases where a low pH value is a problem, it can be neutralized with calcium carbonate. In other cases, it is advisable to add triethanolamine for neutralization, in which case triethanolamin phosphate (TEP) is formed, which is also known to be an effective corrosion inhibitor for steels.
- TEP triethanolamin phosphate
- the products according to the invention are often not only usable as rheology modifiers, but also as fungicides, bakericides and algicides.
- Bentonite a quaternary ammonium compound as dimethophosphate and a stoichiometric amount of triethanolamine are reacted together with the components of a color formulation in a mixing device with high shear forces. The result is a homogeneous color with high corrosion protection for ferrous metals.
