Definitions
- the present invention relates to granulated solids which contain alkyl polyglycosides in combination with polymers and an agrochemical active ingredient, and to a process for the preparation of such compositions.
- nonionic surfactants are in principle particularly suitable auxiliaries for the formulation of crop protection agents, since they have excellent properties both in terms of their toxicology and in terms of their ecological acceptance. Furthermore, they are particularly suitable for improving the spreading of the agents on the plant surface, but also the penetration of the active ingredients into the plant. However, especially with higher proportions of these alkyl polyglycosides in the agents, there is the problem that the solids produced in this way have a poor dissolution rate in water. In addition, due to the production of aqueous pastes as the basis for later granulation, considerable amounts of energy have to be used in the production of the agents.
- WO 03/039249 The improvement in the solubility of granules containing crop protection agents is the subject of various patent applications, reference being made in particular to WO 03/039249.
- the technical teaching of this document provides that mixtures of crop protection agents with a polymer which must contain both hydrophilic and hydrophobic monomers are mixed together and converted into a dry end product.
- Suitable auxiliary substances include alkyl polyglycosides, without the document providing a specific exemplary description of such agents.
- WO 98/33383 discloses solids containing alkyl polyglycosides in admixture with herbicides of the sulfonylurea type. The examples show men that only water is used as the granulating liquid, which is removed from the end products by drying.
- the present invention is therefore based on the object of providing agents with a high content of alkyl polyglycosides which contain agrochemical active ingredients and in particular crop protection agents and are nevertheless readily water-soluble.
- the solids contain alkyl polyglycosides (short name: APG) in amounts of up to 80% by weight. Preferably in amounts of 1 to 45% by weight, it being preferred that the compositions contain 5 to 25 and in particular 5 to 15% by weight of alkyl polyglycosides, based on the total composition.
- APG alkyl polyglycosides
- Alkyl and alkenyl oligoglycosides are known nonionic surfactants which follow the formula RO- [G] p , in which R is an alkyl and / or alkenyl radical having 4 to 22 carbon atoms, G is a sugar radical having 5 or 6 carbon atoms and p for numbers from 1 to stands for a sugar residue with 5 or 6 carbon atoms and p stands for numbers from 1 to 10. They can be obtained according to the relevant methods of preparative organic chemistry.
- the alkyl and / or alkenylogoglycosides can be derived from aldoses or ketoses with 5 or 6 carbon atoms, preferably glucose.
- the preferred alkyl and / or alkenyl ogoglycosides are thus alkyl and or alkenyl ogoglucosides.
- Alkyl and or or alkenylohogoglycosides with an average degree of ohgomization p of 1J to 3.0 are preferably used. From an application point of view, those alkyl and or alkenylohogoglycosides are preferred whose degree of oligomerization is less than 2.0 and in particular between 1.2 and 1.7, preferably between 1.2 and 1.4.
- the alkyl or alkenyl radical R can be derived from primary alcohols having 4 to 11, preferably 8 to 10, carbon atoms. Typical examples are butanol, capro alcohol, caprylic alcohol, cap alcohol and undecyl alcohol and their technical mixtures, such as those used in the hydrogenation of technical Fatty acid methyl esters or in the course of the hydrogenation of aldehydes from Roelen's oxosynthesis are preferred.
- the alkyl or alkenyl radical R can also be derived from primary alcohols having 12 to 22, preferably 12 to 14, carbon atoms.

- fluidized bed granulation In addition to the production by fluidized bed granulation, other production processes are also possible, such as spray drying or preferably extrusion. However, the preferred method for producing granules is fluidized bed granulation. This is understood to mean granulation with simultaneous drying, which is preferably carried out batchwise or continuously.
- the surfactants and polymers according to the invention can optionally be used in combination with other ingredients both in the dried state and as an aqueous or pasty preparation.
- agents according to the invention by first granulating components (A) and (B) with one another and then reacting these granules with components (C) and optionally (D) for the final formulation, preferably likewise by granulation or extrusion ,
- the solids can also be prepared by adding components (A) and (B) in granulated form, preferably by fluidized bed granulation, to components (C) and, if appropriate, (D), and adding water , and this mixture is then optionally extruded into granules.
- the mixtures of the granulated primary products and the other components can be used without further processing or preferably processed into end products by extrusion.
- Another object of the present application relates to the use of granules as described above for the production of crop protection agents.
- An aqueous C8-C10 alkyl polyglucoside paste (60% by weight APG; 40% by weight water) was mixed with an aqueous polyacrylic acid sodium salt (45% by weight polymer; 55% by weight water; MW 4500) in a weight ratio Mixed 1: 1.
